Title: System and method for liquid fuel production from carbonaceous materials using recycled conditioned syngas

Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This application is a continuation application of, and claims priority to, U.S. patent application Ser. No. 16/814,892, for “System and Method for Liquid Fuel Production from Carbonaceous Materials Using Recycled Conditioned Syngas”, filed on Mar. 10, 2020, now allowed. The disclosure of the foregoing applications are incorporated here by reference. 
    
    
     TECHNICAL FIELD 
     The present disclosure is directed to systems and methods for the production of liquid fuels and chemicals from carbonaceous materials. More particularly, it concerns such systems and methods in which a portion of conditioned syngas produced during the process is recycled to help produce additional syngas. 
     BACKGROUND 
     In recent years, there has been a shift towards innovative energy and environmental technologies to moderate climate change, reduce greenhouse gas emissions, reduce air and water pollution, promote economic development, expand energy supply options, increase energy security, decrease dependence on imported oil, and strengthen rural economies. 
     One of these technologies entails conversion of a carbonaceous feedstock into a product gas which can then be converted into liquid fuels, hydrocarbons and other useful compounds. Carbonaceous feedstock along with one or more gaseous or liquid reactants are introduced into a pressurized reactor where they undergo one or more thermochemical reactions to produce the product gas. Ideally, the carbonaceous feedstock is introduced into the reactor such that: feedstock throughput is high, the feedstock has high surface area to promote thermochemical reactions, the feedstock is distributed within the reactor, and the pressure of the reactor is maintained, even as the carbonaceous feedstock is continuously being introduced into the reactor. 
     A liquid fuels production system should be able to produce liquid fuels from large quantities of carbonaceous materials. However, processing large quantities of carbonaceous materials requires having sufficient throughput in each of a number of serially connected systems. These include feeder systems, gas production systems, gas clean-up systems, synthesis systems and gas upgrading systems. The capacities of the various systems should be selected so that they collectively cooperate to meet up-time and fuel production requirements while also maximizing the return on investment (ROI). 
     SUMMARY 
     In one aspect, the subject matter of the present application is directed to a method of producing liquid fuel and/or chemicals from a carbonaceous material. The method includes providing a steam reformer having a plurality of pulse combustion heat exchangers in thermal contact with a particulate heat transfer material. Carbonaceous material is introduced into the steam reformer along with superheated steam. A first portion of conditioned syngas is combusted in the pulse combustion heat exchangers to thereby indirectly heat the particulate heat transfer material and cause the carbonaceous material to react with the superheated steam and produce a first reactor product gas which includes at least carbon monoxide, carbon dioxide, hydrogen, and hydrocarbons. In a hydrocarbon reformer, a second portion of conditioned syngas, an oxygen-containing gas and at least a portion of the first reactor product gas are reacted to produce an improved syngas having a higher concentration of carbon monoxide and a lower concentration of hydrocarbons than in the first reactor product gas. The improved syngas is subjected to one or more gas clean-up steps to produce new conditioned syngas. A first portion of the new conditioned syngas in transferred to a synthesis system to produce tail gas and at least one from the group consisting of liquid fuel and chemicals. A second portion of the new conditioned syngas is transferred to the steam reformer for use as the first portion of conditioned syngas, and to the hydrocarbon reformer for use as the second portion of conditioned syngas. 
     In another aspect, the subject matter of the present application is directed to a system for producing liquid fuel and/or chemicals from a carbonaceous material. The system includes a steam reformer, a hydrocarbon reformer, at least one gas clean-up system and a synthesis system. 
     The steam reformer has a plurality of pulse combustion heat exchangers in thermal contact with a particulate heat transfer material, the steam reformer connected to a source of carbonaceous material and a source of superheated steam, the pulse combustion heat exchangers connected to a first source of conditioned syngas for combusting therein to indirectly heat the particulate heat transfer material and cause the carbonaceous material to react with the superheated steam and produce a first reactor product gas which includes at least carbon monoxide, carbon dioxide, hydrogen and hydrocarbons. 
     The hydrocarbon reformer is connected to a second source of conditioned syngas, a source of oxygen-containing gas and further configured to receive a portion of the first reactor product gas, the hydrocarbon reformer configured to produce an improved syngas having a higher concentration of carbon monoxide and a lower concentration of hydrocarbons than in the first reactor product gas. 
     The at least one gas clean-up system is configured to receive the improved syngas and remove at least one contaminant in the improved syngas to produce a new conditioned syngas, the at least one gas clean-up system having a gas clean-up system output through which the new conditioned syngas exits. 
     The synthesis system is connected to the gas clean-up system output and configured to receive a first portion of the new conditioned syngas and output: (i) tail gas, and (ii) at least one from the group consisting of liquid fuel and chemicals. The gas clean-up system output serves as the first source of conditioned syngas connected to the pulse combustion heat exchangers, and also serves as the second source of conditioned syngas connected to the hydrocarbon reformer.

     DETAILED DESCRIPTION 
     Notation and Nomenclature 
     Before the disclosed systems and processes are described, it is to be understood that the aspects described herein are not limited to specific embodiments, apparatus, or configurations, and as such can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and, unless specifically defined herein, is not intended to be limiting. 
     The idea of a control volume is an extremely general concept used widely in the study and practice of chemical engineering. Control volumes may be used in applications that analyze physical systems by utilization of the laws of conservation of mass and energy. They may be employed during the analysis of input and output data of an arbitrary space, or region, usually being a chemical process, or a portion of a chemical process. They may be used to define process streams entering a single piece of chemical equipment that performs a certain task, or they may be used to define process streams entering a collection of equipment, and assets which work together to perform a certain task. 
     With respect to the surrounding text, a control volume is meaningful in terms of defining the boundaries of a feedstock delivery or a particular product gas generation sequence step or a sequence step related to the overarching topography of an entire biorefinery superstructure system. The arrangements of equipment contained within each control volume are the preferred ways of accomplishing each sequence step. Furthermore, all preferred embodiments are non-limiting in that any number of combinations of unit operations, equipment and assets, including pumping, piping, and instrumentation, may be used as an alternate. However, it has been our realization that the preferred embodiments that make up each sequence step are those which work best to generate a product gas from a carbonaceous material using a feedstock delivery system integrated with at least one thermochemical reactor that cooperates to efficiently and substantially completely convert a carbonaceous material into product gas. In embodiments, successive upstream and downstream thermochemical reactors are implemented and integrated together with a feedstock delivery system and configured to share heat from successive endothermic and exothermic reactions. Nonetheless, any types of unit operations or processes may be used within any control volume shown as long as it accomplishes the goal of that particular sequence step. 
     As used herein the term “carbonaceous material” refers to a solid or liquid substance that contains carbon such as for instance, agricultural residues, agro-industrial residues, animal waste, biomass, cardboard, coal, coke, energy crops, farm slurries, fishery waste, food waste, fruit processing waste, lignite, municipal solid waste (MSW), paper, paper mill residues, paper mill sludge, paper mill spent liquors, plastics, refuse derived fuel (RDF), sewage sludge, tires, urban waste, wood products, wood wastes and a variety of others.

     As used herein the term “char” refers to a carbon-containing solid residue derived from a carbonaceous material and is comprised of the “fixed carbon feedstock components” of a carbonaceous material. Char also includes ash. 
     As used herein the term “char-carbon” refers to the mass fraction of carbon that is contained within the char transferred from the first reactor to the second reactor. 
     As used herein the term “char-ash” refers to the mass fraction of ash that is contained within the char transferred from the first reactor to the second reactor. 
     As used herein the term “fixed carbon feedstock components” refers to feedstock components present in a carbonaceous material other than volatile feedstock components, contaminants, ash or moisture. Fixed carbon feedstock components are usually solid combustible residue remaining after the removal of moisture and volatile feedstock components from a carbonaceous material. 
     As used herein the term “volatile feedstock components” refers to components within a carbonaceous material other than fixed carbon feedstock components, contaminants, ash or moisture. 
     As used herein the term “inert feedstock contaminants” or “inert contaminants” refers to Geldart Group D particles contained within a MSW and/or RDF carbonaceous material. Geldart Group D solids comprise whole units and/or fragments of one or more of the group consisting of allen wrenches, ball bearings, batteries, bolts, bottle caps, broaches, bushings, buttons, cable, cement, chains, clips, coins, computer hard drive shreds, door hinges, door knobs, drill bits, drill bushings, drywall anchors, electrical components, electrical plugs, eye bolts, fabric snaps, fasteners, fish hooks, flash drives, fuses, gears, glass, gravel, grommets, hose clamps, hose fittings, jewelry, key chains, key stock, lathe blades, light bulb bases, magnets, metal audio-visual components, metal brackets, metal shards, metal surgical supplies, mirror shreds, nails, needles, nuts, pins, pipe fittings, pushpins, razor blades, reamers, retaining rings, rivets, rocks, rods, router bits, saw blades, screws, sockets, springs, sprockets, staples, studs, syringes, USB connectors, washers, wire, wire connectors, and zippers. 
     Generally speaking, Geldart grouping is a function of bed material particle size and density and the pressure at which the fluidized bed operates.

     A sensor is typically referred to as a type of control loop hardware that is equipped to measure a specific process variable or sensed value and transmit that measurement to a controller, or to a control computer, or to both. Examples of process variables include, but are not limited to, flow rates, pressures, temperatures, product gas compositions, ratio of constituents within the product gas composition (e.g.—hydrogen to carbon monoxide ratio, or carbon monoxide to carbon dioxide ratio), and carbonaceous material composition such as (i) ultimate analysis (C, H, O), (ii) proximate analysis, and/or (iii) energy content of a carbonaceous material. Carbon is typically a constituent of a carbonaceous material and typically carbon is a process variable obtained through the methods which involve obtaining the ultimate analysis of a carbonaceous material. The carbon content of a carbonaceous material may be a process variable measured or obtained by a sensor. The hydrogen content of a carbonaceous material may be a process variable measured or obtained by a sensor. The oxygen content of a carbonaceous material may be a process variable measured or obtained by a sensor. And, in turn, the ultimate analysis of a carbonaceous material, which includes the carbon, hydrogen and/or oxygen may also be a process variable measured or obtained by one sensor or multiple sensors. 
     In some embodiments, the present disclosure places emphasis on carbonaceous material quality verification and process integration via utilization of various fast, reliable, mobile, wireless, low in cost, widely available, and easy to use sensors that may be adapted to measure process variables and capable of integration with advanced process control schemes including feedback, feedforward, back-pressure, ratio, cascade, or differential. 
     In some embodiments, the present disclosure describes a robust feedstock delivery system that is configured to accommodate widely variable feedstocks irrespective to variation in geographic diversity or seasonal changes and consistently produce a carbonaceous material having predictable and reliable characteristics while at the same time being integrated with an advanced feedstock delivery system capable of employing advanced logic control, logistics, and sophisticated inventory management methods to improve facility availability, reliability, and consistently meet performance targets. 
     In some embodiments, the present disclosure emphasizes innovation related to a versatile feedstock preparation and delivery system adapted to utilize sophisticated logistics systems for carbonaceous materials that result in superior operational flexibility to accommodate feedstock variability, and resultantly improve feedstock availability for delivery, reliability of feedstock supply, and consistent feedstock quality, while using control logic to integrate signals from measurements and sensors of carbonaceous material composition with downstream process controllers, actuators, and valves. 
     In some embodiments, the present disclosure emphasizes the use of simple, timely, accurate instruments to verify or measure feedstock quality specifications at points of collection, consolidation, delivery, or storage, and integrate signals from measurements and sensors with downstream process controllers, actuators, and valves. In some embodiments, the present disclosure emphasizes the use of fast, simple, and inexpensive devices to accurately determine carbonaceous material quality and integrate signals from measurements and sensors with downstream process controllers, actuators, and valves. 
     Various process control methodologies may be used throughout the various non-limiting embodiments of the disclosure. For example, (a) feedback, (b) feed-forward, and (c) ratio control are some of the high priority control schemes that may be incorporated to realize efficient process optimization for economical operation of the described feedstock delivery and product gas generation system. Some control systems will have one or more of the aforesaid type of control schemes which may or may not cooperate together to realize efficient energy integration and maximize carbon conversion between the two successive thermochemical reaction environments. 
     Selection of the most suitable control loop hardware and control plant control logic and methodologies plays an important position in development and commercialization of economically attractive technologies to convert carbonaceous materials into valuable products and energy. Control loop hardware generally includes sensors, controllers, and actuators. Sensors, controllers, and actuators are typically mechanical, electrical, digital devices, or combinations of each. Sensors are usually configured to measure process variables either continuously or discretely by taking individual periodic measurements at discrete times. Flow rate, pressure, and temperature are typically process variables or sensed values that are available or measured continuously, however, these variables may also be obtained through discrete measurements updated at discrete times. Product gas composition and carbonaceous material composition such as (i) ultimate analysis (C, H, O), (ii) proximate analysis, (iii) energy content, or (iv) water content of a carbonaceous material are typically process variables that are available or measured through discrete measurements updated at discrete times, however these variables may also be obtained continuously. 
     Product gas composition and carbonaceous material composition such as (i) ultimate analysis (C, H, O), (ii) proximate analysis, and/or (iii) energy content of a carbonaceous material are process variables that are typically obtained through discrete measurements updated at discrete times, however, these variables may be read continuously as well, due to advancements in analytical data acquisition technologies with advanced capabilities. Nonetheless, although modern advancements have made mechanical, electrical, and digital sensor devices commercially available which continuously measure process variables, such as product gas composition and carbonaceous material composition, the focus of this disclosure is to expand upon the art through specific improved advancements related to selection and/or implementation of the control logic behind various process control schemes and high priority control loops. The exact type of preferred sensors contemplated in the disclosure are of varying priority when compared to the preferred selection of important control loops and logic schemes that utilize or incorporate process variables or sensed values obtained from such sensors. Thus in turn, the exact types of preferred sensors contemplated in the disclosure may in some instances be, in fact, improvements over the level of art known at the time of filing and as a result are of paramount importance with respect to the selection of logic behind utilizing the sensed values obtained from such sensors. 
     A control computer (COMP) is configured to accept a variety of signals from process variables using a variety of sensors and/or controllers, and then apply advanced process logic control methodologies, strategies and/or sequences to realize modulation of actuators and/or valves to effectuate optimal operation of the feedstock delivery and product gas generation system. A process controller or control computer applies the control approach and methodology for the entire control loop on a continuous basis, a discrete basis, or a hybrid combination of a continuous basis and a discrete basis. Further, a control computer may be applied to implement the control methodology by utilizing process variables obtained by either a continuous sensor, a discrete sensor, or a combination of a continuous sensor and a discrete sensor and hold the control action at a constant set-point at that specific control output until a later time when that control algorithm is executed. The time between successive interrogations or application of the control algorithm is applied by the control computer is defined as the control interval. The control interval for a continuous sensor is typically shorter than that of a discrete sensor and based upon commercially available mechanical, electrical, or digital continuous or discrete sensors, the control interval or control time can vary from 0.2 milliseconds, to 0.5 seconds, to 1.0 second, to 10 seconds, to 30 seconds, to 1 minute, to 5 minutes, to 10 minutes, to 30 minutes, to 1 hour, to 10 hours, or longer. The output from the control computer is transmitted to a controller device. From application of the control logic, the control computer can send a variety of signals to a variety of controllers. A wide variety of sensor technologies exist for measuring the composition of carbonaceous materials. Some of the categories of commercially available sensor technologies that may be used in the analysis of carbonaceous materials are electric, digital, acoustic, microwave, terahertz, NIR, FTIR, Raman spectroscopy, and X-ray. 
     Advancements in the art of sensors can provide continuous or discrete measurement of (i) ultimate analysis (C, H, O), (ii) proximate analysis, or (iii) energy content of a carbonaceous material that may often be characterized as an unpredictable and often wet substance, such as MSW. Typically, such sensors also require that the carbonaceous material is conveyed past the sensor by a mechanical or pneumatic device such as a conveyor belt or bucket elevator or carbonaceous feeder system such as a lock hopper system, rotary feeder, plug-forming feeder, non-plug-forming feeder, extrusion and/or injection system, and/or pneumatic feed system. However, the preferred method of utilizing such sensors incorporates a conveyor belt installed upstream of a multi-stage piston feeder. 
     Any conceivable type of material conveyance system or feeder system may be utilized as long as the carbonaceous material is made available to the sensor to measure either at least one of the (i) ultimate analysis (C, H, and/or O), (ii) proximate analysis, and/or (iii) energy content of a carbonaceous material. It is preferred that the carbonaceous material is made accessible to the sensor or group of sensors to measure the (i) ultimate analysis (C, H, and/or O), (ii) proximate analysis, and/or (iii) energy content of a carbonaceous material in a spread-out fashion over a conveyor belt, in a screw conveyor, as a plug, de-densified carbonaceous material, or in any other conceivable fashion insofar as the sensor is positioned in an accessible manner to allow the sensor to analyze the carbonaceous material. 
     Of particular interest in the present disclosure is the preferred sensor used to measure the (i) ultimate analysis, or at least one of the carbon, hydrogen, and/or oxygen content of a carbonaceous material transported to the reactor is of the X-ray type sensor which beams through, at, or upon the carbonaceous material to measure at least one of the carbon, hydrogen, or oxygen content of the carbonaceous material in either a continuous or discrete manner. 
     Of particular interest in the present disclosure is the preferred sensor used to measure (ii) proximate analysis, or at least the volatiles content or fixed carbon content of a carbonaceous material is that of a thermogravimetric analyzer (TGA) type which allows for a continuous or discrete measurement of either or both of the volatile content or fixed carbon content components of a carbonaceous material. 
     Of particular interest in the present disclosure is the preferred sensor used to measure (iii) energy content of a carbonaceous material which is a combination of two sensors including a Raman technique sensor and an X-ray analysis technique sensor to obtain chemical composition and density data of the carbonaceous material, respectively, and then fuse each sensed value data together into approximate energy concentrations to obtain the energy content of the carbonaceous material in either a continuous or discrete manner. Alternatively, in some non-limiting embodiments, it may be preferred to use a single sensor that utilizes a Raman technique together with an X-ray analysis technique to obtain carbonaceous material chemical composition and carbonaceous material density data, respectively, and then fuse this data together into approximate energy concentrations to obtain an energy content of the carbonaceous material in either a continuous or discrete manner. Such a sensor that is a combination of Raman and X-ray analysis techniques in some embodiments is the preferred sensor to measure the energy content of a carbonaceous material, however any type of energy content sensor and/or system and/or method may be employed to accomplish the goal of measuring the energy content of a carbonaceous material. Furthermore, as methods to probe more intricate physical characteristics become more commonplace, some manner of correlational relationships could potentially be developed and improved upon. Nonetheless, the preferred method for obtaining a continuous or discrete measurement of the energy value of the carbonaceous material includes an assessment of the approximate chemical composition towards an energy value and is achieved preferably with a sensor or sensors that take a combination of several different source/detector pairs to obtain a continuous or discrete measurement of the energy content of the carbonaceous material. 
     Such aforementioned analytical techniques work for a wide range of carbonaceous materials and preferably analyze the carbonaceous material as it is spread-out on a conveyor or within a screw conveyor before it gets to the first reactor. Nonetheless, the methods disclosed herein are not limited to any specific sensor or technique to measure the (i) ultimate analysis (C, H, and/or O), (ii) proximate analysis, and/or (iii) energy content of a carbonaceous material, but instead, the non-limiting embodiments contemplated in this disclosure are directed towards the application of the process variables or sensed values obtained from such sensors. Further, any sort of commercially available sensor or combination of sensors may be used so long as the sensor or sensors measure the process variables or sensed values of (i) ultimate analysis (C, H, and/or O), (ii) proximate analysis, and/or (iii) energy content of a carbonaceous material transferred to the first reactor. Any type of sensor may be used to measure either the carbon content, hydrogen content, oxygen content, volatiles content, fixed carbon content, and/or energy content of a carbonaceous material in a continuous or discrete manner so long as the sensor or sensors provide a process controller with the process variables or sensed values of the sensors analyzing the carbonaceous material.

       FIG.  5    elaborates upon the non-limiting embodiment of  FIG.  2 A  further including a description of the Mass Flow Regulation ( 2 C) subsystem or sequence step of the Feedstock Delivery System ( 2000 ). 
     Each of the plurality of outputs ( 2 B-OUT 1 ,  2 B-OUT 1 A,  2 B-OUT 1 B,  2 B-OUT 1 C,  2 B-OUT 1 D,  2 B-OUT 1 E,  2 B-OUT 1 F) from the Flow Splitting ( 2 B) subsystem of  FIG.  4    may be provided to a plurality of inputs ( 2 C-IN 1 A,  2 C-IN 1 B,  2 C-IN 1 C,  2 C-IN 1 D,  2 C-IN 1 E,  2 C-IN 1 F) to the downstream Mass Flow Regulation ( 2 C) subsystems as depicted in  FIG.  5   . 
       FIG.  5    shows one example of a Mass Flow Regulation ( 2 C) subsystem accepting a carbonaceous material ( 2 C- 01 ) as an input ( 2 C-IN 1 A) from a first output ( 2 B-OUT 1 A) of a Flow Splitting ( 2 B) subsystem. 
     The Mass Flow Regulation ( 2 C) subsystem is shown contained within a Mass Flow Regulation Control Volume (CV- 2 C). The Mass Flow Regulation ( 2 C) subsystem is configured to accept a carbonaceous material ( 2 C- 01 ) input ( 2 C-IN 1 A) from at least one of the outputs ( 2 B-OUT 1 A) from the Flow Splitting ( 2 B) subsystem of  FIG.  4   , and discharge a stream of carbonaceous material ( 2 C- 02 ) via an output ( 2 C-OUT 1 A). The Mass Flow Regulation ( 2 C) subsystem is also configured to accept a gas ( 2 C- 03 ) via a gas input ( 2 C-IN 2 A). The gas ( 2 C- 03 ) is preferably air, however it can be nitrogen, carbon dioxide, or product gas. The carbonaceous material ( 2 C- 02 ) output ( 2 C-OUT 1 A) from the Mass Flow Regulation Control Volume (CV- 2 C) is the input ( 2 D-IN 1 ) to a downstream Densification Control Volume (CV- 2 D) shown in  FIG.  6   . 
     A weigh feeder ( 2 C 1 ) is used to regulate the mass flow rate of the carbonaceous material ( 2 C- 01 ) passing from the feeder input ( 2 C- 05 ) to the feeder output ( 2 C- 06 ). The weigh feeder ( 2 C 1 ) has a feeder input ( 2 C- 05 ) and a feeder output ( 2 C- 06 ). The feeder input ( 2 C- 05 ) is synonymous with the feed zone delivery system input ( 2 C- 04 A) as disclosed in  FIG.  14   . 
     The weigh feeder ( 2 C 1 ) is comprised of a receiving unit ( 2 C- 07 ) and a transport unit ( 2 C- 22 ). The receiving unit ( 2 C- 07 ) has an interior ( 2 C 1 IN) defined by at least one side wall ( 2 C- 08 ) having a height ( 2 C- 08 H), width ( 2 C- 08 W), and length ( 2 C- 08 L), that constitute a volume ( 2 C-V 1 ) (not shown). The receiving unit ( 2 C- 07 ) may be cylindrical, rectangular, trapezoidal or any other conceivable shape. The receiving unit ( 2 C- 07 ) has a top opening ( 2 C- 11 ) at a top section ( 2 C- 09 ) and a bottom opening ( 2 C- 12 ) at a bottom section ( 2 C- 10 ). The feeder input ( 2 C- 05 ) is located at a top section ( 2 C- 09 ) and the bottom section ( 2 C- 10 ) is in fluid communication with a transport unit ( 2 C- 22 ). The feeder input ( 2 C- 05 ) is preferably positioned in a top opening ( 2 C- 11 ) at the top section ( 2 C- 09 ) of the receiving unit ( 2 C- 07 ). The receiving unit ( 2 C- 07 ) is configured to receive carbonaceous material ( 2 C- 01 ) to the interior ( 2 C 1 IN) via a feeder input ( 2 C- 05 ). 
     The side wall ( 2 C- 08 ) of the receiving unit ( 2 C- 07 ) is equipped with a connection (C-P 1 C) for a first proximity sensor (C-P 1 ) which is configured to output a signal (XCP 1 ) to the computer (COMP) when carbonaceous material is within close proximity to the first proximity sensor (C-P 1 ). A first gas nozzle ( 2 C- 15 ) with a first gas supply ( 2 C- 14 ) is located immediately within the vicinity above the first proximity sensor (C-P 1 ) and configured to blow off carbonaceous material dust which may build up on top of the first proximity sensor (C-P 1 ). The side wall ( 2 C- 08 ) of the receiving unit ( 2 C- 07 ) is equipped with a connection (C-P 2 C) for a second proximity sensor (C-P 2 ) which is configured to output a signal (XCP 2 ) to the computer (COMP) when carbonaceous material is within close proximity to the second proximity sensor (C-P 2 ). A second gas nozzle ( 2 C- 17 ) with a second gas supply ( 2 C- 16 ) is located immediately within the vicinity above the second proximity sensor (C-P 2 ) and configured to blow off carbonaceous material dust which may build up on top of the second proximity sensor (C-P 2 ).  FIG.  5    shows the first proximity sensor (C-P 1 ) connection (C-P 1 C) located at a vertical height lesser than and below the second proximity sensor (C-P 2 ) connection (C-P 2 C). 
     In embodiments, a proximity sensor may be a capacitive-type sensor such as model #CJ10-30GM-E2 marketed by Pepperl+Fuchs™. Capacitive sensing is a technology, based on capacitive coupling, that can detect and measure the presence or absence of carbonaceous material which has a dielectric different from air. Many types of sensors use capacitive sensing, including sensors to detect and measure proximity or level. Proximity sensors are equivalent to level sensors. Capacitive proximity switches are dependent on the material characteristics of the carbonaceous material. When a dielectric material, such as carbonaceous material, is placed in the electric field emitted by a proximity sensor, electric charges do not flow through the material, but only slightly shift from their average equilibrium positions causing dielectric polarization. In embodiments, dust or carbonaceous material can build up on the proximity sensor and therefore a supply of gas is needed to continuously purge the sensor to clear accumulation of dust or carbonaceous material on the sensor. Accumulation or build-up of dust or carbonaceous material on the proximity sensor may result in a false reading where the sensor indicates that a carbonaceous material is present at the height of the sensor when in fact it is not. 
     For illustrative purposes,  FIG.  5    shows dust accumulation (C 2 D) on the second proximity sensor (C-P 2 ). The purpose of the second gas nozzle ( 2 C- 17 ) is to provide a first gas supply ( 2 C- 16 ) to the second proximity sensor (C-P 2 ) to avoid and prevent dust accumulation (C 2 D). The presence of dust accumulation (C 2 D) on any portion of the first proximity sensor (C-P 2 ) may result in a false signal (XCP 2 ) from the second proximity sensor (C-P 2 ) to the computer (COMP). Dust accumulation (C 2 D) on the second proximity sensor (C-P 2 ) results in the signal (XCP 2 ) to the computer (COMP) indicating that the second proximity sensor (C-P 2 ) reads a level of carbonaceous material within the interior ( 2 C 1 IN) of the receiving unit ( 2 C- 07 ) at a first sensor height ( 2 C- 08 H), when in fact, it is not. 
     The side wall ( 2 C- 08 ) of the receiving unit ( 2 C- 07 ) is equipped with a third gas connection ( 2 C- 19 ) configured to introduce a third gas supply ( 2 C- 18 ) along the width ( 2 C- 08 W) of the receiving unit ( 2 C- 07 ) of the weigh feeder ( 2 C 1 ) to prevent bridging of the carbonaceous material ( 2 C- 01 ) between the feeder input ( 2 C- 05 ) to the feeder output ( 2 C- 06 ). The side wall ( 2 C- 08 ) of the receiving unit ( 2 C- 07 ) is equipped with a fourth gas connection ( 2 C- 21 ) configured to introduce a fourth gas supply ( 2 C- 20 ) along the width ( 2 C- 08 W) of the receiving unit ( 2 C- 07 ) of the weigh feeder ( 2 C 1 ) to prevent bridging of the carbonaceous material ( 2 C- 01 ) between the feeder input ( 2 C- 05 ) to the feeder output ( 2 C- 06 ).  FIG.  5    shows the fourth gas connection ( 2 C- 21 ) located at a vertical height lesser than and below the third gas connection ( 2 C- 19 ). 
     The bottom section ( 2 C- 10 ) of the receiving unit ( 2 C- 07 ) is in fluid communication with the transport unit ( 2 C- 22 ). The transport unit ( 2 C- 22 ) has an interior ( 2 C- 23 ) defined by at least one side wall ( 2 C- 24 ). The transport unit ( 2 C- 22 ) has a height ( 2 C- 22 H) (not shown), width ( 2 C- 22 W) (not shown), and length ( 2 C- 22 L) that constitute a volume ( 2 C-V 2 ) (not shown).  FIG.  5    does not show the height ( 2 C- 22 H) (not shown), nor width ( 2 C- 22 W) (not shown), because they equal each other if the transport unit ( 2 C- 22 ) takes the form of a circular cross-section and as a result only a diameter ( 2 C- 22 D) is shown. It is to be noted that the geometry of the transport unit ( 2 C- 22 ) may be circular, rectangular, trapezoidal, or any other shape. 
     Carbonaceous material ( 2 C- 01 ) is transferred from the interior ( 2 C 1 IN) of the receiving unit ( 2 C- 07 ) to the interior ( 2 C- 23 ) of the transport unit ( 2 C- 22 ). A screw conveyor ( 2 C- 25 ) has a shaft ( 2 C- 26 ) equipped with a shaft rotation measurement unit ( 2 C- 27 ) and a motor (M 2 C) with a controller (C-M 2 C) is disposed within the interior ( 2 C- 23 ) of the transport unit ( 2 C- 22 ). The shaft rotation measurement unit ( 2 C- 27 ) is configured to input and output a signal (X 2 C 27 ) to or from the computer (COMP) indicative of the rotations per minute (RPM) of the shaft ( 2 C- 26 ) of the screw conveyor ( 2 C- 25 ). The controller (C-M 2 C) of the motor (M 2 C) is configured to input and output a signal (XM 2 C) to or from the computer (COMP) to rotate the shaft ( 2 C- 26 ) of the screw conveyor ( 2 C- 25 ). 
     A weight measurement unit ( 2 C- 30 ) is operatively coupled to the weigh feeder ( 2 C 1 ). The embodiment shown in  FIG.  5    shows the weight measurement unit ( 2 C- 30 ) including a first mass sensor (W 2 C- 1 ) and a second mass sensor (W 2 C- 2 ) located at opposing ends along the length ( 2 C- 22 L) of the transport unit ( 2 C- 22 ). The first mass sensor (W 2 C- 1 ) is located at a first transport unit connection (CT 1 ) along the length ( 2 C- 22 L) of the transport unit ( 2 C- 22 ). The second mass sensor (W 2 C- 2 ) is located at a second transport unit connection (CT 2 ) along the length ( 2 C- 22 L) of the transport unit ( 2 C- 22 ). The first mass sensor (W 2 C- 1 ) is configured to output a first signal (X 2 WC 1 ) to the computer (COMP). The second mass sensor (W 2 C- 2 ) is configured to output a second signal (X 2 WC 2 ) to the computer (COMP). 
     In embodiments, each mass sensor (W 2 C- 1 , W 2 C- 2 ) is preferably of the compression load cell, tension cell, or shear cell type, however other types may be utilized as well. Each mass sensor (W 2 C- 1 , W 2 C- 2 ) shown in  FIG.  5    is displayed beneath the weigh feeder ( 2 C 1 ) so that the weigh feeder ( 2 C 1 ) is pressing onto each mass sensor (W 2 C- 1 , W 2 C- 2 ) and each mass sensor (W 2 C- 1 , W 2 C- 2 ) is connected to the transport unit ( 2 C- 22 ) via a first transport unit connection (CT 1 ) and a second transport unit connection (CT 2 ).

     Specifically, the transport unit ( 2 C- 22 ) is equipped with a connection ( 2 C-CCC) for a carbon content measurement unit ( 2 C-CC) that is configured to analyze carbonaceous material transported from the through the weigh feeder ( 2 C 1 ) and send a signal (X 2 CCC) to the computer (COMP) to output the carbon content ( 2 C- 02 CC) of the carbonaceous material ( 2 C- 02 ) discharged from the transport unit ( 2 C- 22 ). 
     The transport unit ( 2 C- 22 ) is equipped with a connection ( 2 C-EC) for an energy content measurement unit ( 2 C-BTU) that is configured to analyze carbonaceous material transported through the weigh feeder ( 2 C 1 ) and send a signal (X 2 CE) to the computer (COMP) to output the energy content ( 2 C- 02 BTU) of the carbonaceous material ( 2 C- 02 ) discharged from the transport unit ( 2 C- 22 ). 
     The transport unit ( 2 C- 22 ) is equipped with a connection ( 2 C-VC) for a volatiles content measurement unit ( 2 C-VOL) that is configured to analyze carbonaceous material transported through the weigh feeder ( 2 C 1 ) and send a signal (X 2 CVOL) to the computer (COMP) to output the volatiles content ( 2 C- 02 VOL) of the carbonaceous material ( 2 C- 02 ) discharged from the transport unit ( 2 C- 22 ).

     (Step  2 C: 2 ) in a second mode of operation, when a signal (XCP 1 ) is triggered from carbonaceous material being in proximity to the first proximity sensor (C-P 1 ) the computer (COMP) sends a signal (XM 2 C) to controller (C-M 2 C) to operate a motor (M 2 C) to rotate a shaft ( 2 C- 26 ) of weigh feeder ( 2 C 1 ) screw conveyor ( 2 C- 25 );

     FIG.  7 : 
       FIG.  7    elaborates upon a non-limiting embodiment of  FIG.  2 A  further including a description of the Densification ( 2 D) subsystem or sequence step of the Feedstock Delivery System ( 2000 ).  FIG.  7    shows one example of a Densification ( 2 D) subsystem accepting a carbonaceous material ( 2 D- 01 ) as an input ( 2 D-IN 1 A) from an output ( 2 C-OUT 1 A) of a Mass Flow Regulation ( 2 C) subsystem. The Densification ( 2 D) subsystem is shown contained within a Densification Control Volume (CV- 2 D). The Densification ( 2 D) subsystem is configured to accept a carbonaceous material ( 2 D- 01 ) at a first lower density ( 2 D- 01 RHO) via an input ( 2 D-IN 1 A) and compress the carbonaceous material to discharge a densified carbonaceous material ( 2 D- 02 ) at a second higher density ( 2 D- 02 RHO) via an output ( 2 D-OUT 1 A). The densified carbonaceous material ( 2 D- 02 ) is then transferred via the output ( 2 D-OUT 1 A) and may be routed downstream, for example, to a Plug Control ( 2 E) subsystem via an input ( 2 E-IN 1 A). The Densification ( 2 D) subsystem of  FIG.  7    includes a densification system ( 2 D 0 ) comprised of a first piston cylinder assembly ( 2 D 1 ), second piston cylinder assembly ( 2 D 2 ), and a third piston cylinder assembly ( 2 D 3 ). 
     In embodiments, the first lower density ( 2 D- 01   rho ) may range from about 4 lb/ft3 to about 14 lb/ft3 for MSW carbonaceous material ( 2 D- 01 ). In embodiments, the first lower density ( 2 D- 01   rho ) may range from about 5 lb/ft3 to about 20 lb/ft3 for other types of carbonaceous materials ( 2 D- 01 ), such as wood, biomass, or the like. In embodiments, the first lower density ( 2 D- 01   rho ) may range from about 20 lb/ft3 to about 50 lb/ft3 for cubed or briquette carbonaceous material ( 2 D- 01 ). 
     In embodiments, the carbonaceous material ( 2 D- 01 ) introduced to the densification system ( 2 D 0 ) is comprised of cubes ready for transport to be used as an energy source. In embodiments, the cubed carbonaceous material ( 2 D- 01 ) introduced to the densification system ( 2 D 0 ) may range from about 0.50 inches to about 3 inches length and formed by use of an upstream cube forming machine. 
     In embodiments, the cubed carbonaceous material ( 2 D- 01 ) introduced to the densification system ( 2 D 0 ) may be formed using a cubing system create a body having a substantially constant cross sectional shape along its length. Densification is an important unit operation involved in utilization of initially lower density material, because it reduces handling, storage and transportation costs. Pelleting and cubing are two prominent existing technologies used for the densification of carbonaceous material feedstocks. The cubing process allows for greater particle size in the finished product as compared to pellets produce in a conventional pellet mill. In embodiments, carbonaceous material is introduced into an upstream cubing system prior to being introduced to the densification system ( 2 D 0 ). Cubing systems are well known in the art and exhibit high compression pressures on the carbonaceous material from about 1,000 PSIG to about 6,000 PSIG as the material to be cubed enters the series of dies to create an effective product which is extruded through the dies. Preferably the carbonaceous material introduced to the densification system ( 2 D 0 ) is first cubed using a substantially square die to form an extruded body of square cross-section and square flakes. However, advancement in the cubing dies may reveal that it is our preference to form an extruded body of circular cross-section using a substantially circular die to form an extruded body of circular cross-section and circular flakes. However, the die could be also any other shape. 
     In embodiments, each plug ( 1 D,  2 D,  3 D,  4 D,  5 D,  6 D) of densified carbonaceous material ( 2 D- 02 ) at a second higher density ( 2 D- 02   rho ) has a length of about 10 inches to 15 inches. In embodiments, each plug ( 1 D,  2 D,  3 D,  4 D,  5 D,  6 D) of densified carbonaceous material ( 2 D- 02 ) at a second higher density ( 2 D- 02   rho ) has a diameter of about 10 inches to 15 inches. In embodiments, each plug ( 1 D,  2 D,  3 D,  4 D,  5 D,  6 D) of densified carbonaceous material ( 2 D- 02 ) at a second higher density ( 2 D- 02   rho ) has a length to diameter ratio of less than 1.5.

     FIG.  7 A: 
       FIG.  7 A  elaborates upon a non-limiting embodiment of  FIG.  7    wherein the Densification ( 2 D) subsystem or sequence step is in fluid communication with an airborne particulate solid evacuation system ( 565 ) via a densification entry conduit ( 563 D). The airborne particulate solid evacuation system ( 565 ) is described in the detail in the text below and accompanied  FIG.  17   . 
       FIG.  7 A  shows a densification entry conduit ( 563 D) equipped to capture airborne particulate solids from the vicinity around each densification system ( 2 D 0 ). Specifically, airborne particulate solids may be removed via the densification entry conduit ( 563 D) from the air surrounding each densifier input (D 13 ) or at the transitions between the (i) first cylinder first flange (D 02 ) and first hydraulic cylinder flange (D 06 ); (ii) second cylinder first flange (D 16 ) and second hydraulic cylinder flange (D 21 ); (iii) third cylinder first flange (D 31 ) and third hydraulic cylinder flange (D 35 ). 
     To mitigate against the risks of fire or deflagration hazards associated with particulate solids suspended in air, active dust or particulate solid evacuation methods are implemented and described. The airborne particulate solid evacuation system ( 565 ) captures airborne particulate solids that would ordinarily escape from the perimeter of the operating equipment of the Densification ( 2 D) subsystem. 
     The high velocity densification entry conduit ( 563 D) operates at a capture velocity sufficient to allow airborne particulate solids to be captured and drawn into the airborne particulate solid evacuation system ( 565 ). In embodiments, the densification entry conduit ( 563 D) operates within a velocity pressure range from about 0.10 inches of water to about 1.50 inches of water. In embodiments, the densification entry conduit ( 563 D) operates with velocity ranging from about 100 feet per minute to about 5000 feet per minute. 
     The densification entry conduit ( 563 D) operates within a velocity pressure range sufficient to pull away fine dust or particulate solids from behind either of the first ram (D 14 ), second ram (D 28 ), of third ram (D 42 ). Shut down will be required if fine dust or particulate solids migrate to and build up behind either the first ram (D 14 ), second ram (D 28 ), of third ram (D 42 ). Eventually as the pistons ( 2 D 1 ,  2 D 2 ,  2  D 3 ) cycle through advancement and retraction modes of operations, fine dust or particulate solids migrate to and build up behind either the first ram (D 14 ), second ram (D 28 ), of third ram (D 42 ) requiring the system to be taken apart and cleaned out wasting precious time. Thus, eventually, fine dust or particulate solids migrate to and build up behind either the first ram (D 14 ), second ram (D 28 ), of third ram (D 42 ) prevents each pistons ( 2 D 1 ,  2 D 2 ,  2  D 3 ) to fully retract. Fine dust or particulate solids accumulate in the following areas about the vicinity around each densification system ( 2 D 0 ): (i) the first ram (D 14 ) and upon the surface of the first hydraulic cylinder flange (D 06 ); (ii) the second ram (D 28 ) and upon the surface of the second hydraulic cylinder flange (D 21 ); (iii) the third ram (D 42 ) and upon the surface of the third hydraulic cylinder flange (D 35 ). 
       FIG.  7 A  shows a densification entry conduit ( 563 D) in fluid communication with a first ram particulate solids evacuation port (D 43 ), a second ram particulate solids evacuation port (D 45 ), and, a third ram particulate solids evacuation port (D 47 ). A first flange support (D 44 ) is provided in between the first cylinder first flange (D 02 ) and first hydraulic cylinder flange (D 06 ) so as to provide secure connection while permitting fine dust or particulate solids to be drawn through the first ram particulate solids evacuation port (D 43 ) and to prevent their accumulation behind the first ram (D 14 ) and upon the surface of the first hydraulic cylinder flange (D 06 ). A second flange support (D 46 ) is provided in between the second cylinder first flange (D 16 ) and second hydraulic cylinder flange (D 21 ) so as to provide secure connection while permitting fine dust or particulate solids to be drawn through the second ram particulate solids evacuation port (D 45 ) and to prevent their accumulation behind the second ram (D 28 ) and upon the surface of the second hydraulic cylinder flange (D 21 ). A third flange support (D 48 ) is provided in between the third cylinder first flange (D 31 ) and third hydraulic cylinder flange (D 35 ) so as to provide secure connection while permitting fine dust or particulate solids to be drawn through the third ram particulate solids evacuation port (D 47 ) and to prevent their accumulation behind the third ram (D 42 ) and upon the surface of the third hydraulic cylinder flange (D 35 ). 
     FIG.  7 B: 
       FIG.  7 B  elaborates upon a non-limiting embodiment of  FIG.  7 A  further including a detailed three dimensional view of a first flange support (D 44 ) that may be placed in between the first cylinder first flange (D 02 ) and the first hydraulic cylinder flange (D 06 ). The first ram particulate solids evacuation port (D 43 ) is in fluid communication with the densification entry conduit ( 563 D) which evacuates solids from behind the first ram (D 14 ). The flange support (D 44 ) allows the first cylinder first flange (D 02 ) and the first hydraulic cylinder flange (D 06 ) to be connected to one another. The first ram particulate solids evacuation port (D 43 ) allows for solids to be transferred from the first cylinder (D 01 ) and into the airborne particulate solid evacuation system ( 565 ). Each of the second ram particulate solids evacuation port (D 45 ), second flange support (D 46 ), third ram particulate solids evacuation port (D 47 ), and third flange support (D 48 ) are similar to the first ram particulate solids evacuation port (D 43 ) and first flange support (D 44 ) shown in  FIG.  7 B .

     The bulk transfer entry conduit ( 563 A) captures airborne particulate solids from the transport assembly ( 2 A- 03 ). The flow splitting entry conduit ( 563 B) captures airborne particulate solids from the first splitter ( 2 B 1 ) and second splitter ( 2 B 2 ). Specifically, airborne particulate solids are shown in  FIG.  4    to be removed via the flow splitting entry conduit ( 563 B) from the first splitter ( 2 B 1 ) and the flow splitting entry conduit ( 563 BA) from the second splitter ( 2 B 2 ). Airborne particulate solids may also be removed via the flow splitting entry conduits ( 563 B,  563 BA) from the first output ( 2 B- 07 ), second output ( 2 B- 09 ), and third output ( 2 B- 11 ) of the first splitter ( 2 B 1 ) and the first output ( 2 B- 16 ), second output ( 2 B- 18 ), and third output ( 2 B- 20 ) of the second splitter ( 2 A 2 ). 
     The mass flow regulation entry conduit ( 563 C) captures airborne particulate solids from each weigh feeder ( 2 C 1 ). Specifically, airborne particulate solids may be removed via the mass flow regulation entry conduit ( 563 C) from receiving unit ( 2 C- 07 ) of each weigh feeder ( 2 C 1 ).

     The solids transfer entry conduit ( 563 E) captures airborne particulate solids from the second solids separation device ( 250 ) and solids transfer conduit ( 234 ). Specifically, airborne particulate solids may be removed via the solids transfer entry conduit ( 563 E) from the solids transfer conduit ( 234 ) with a specific focus on removal of airborne particulate solids from valves which may be positioned in the solids transfer conduit ( 234 ) that regulate the flow of second reactor separated solids ( 232 ). 
     In embodiments, particulate solids may be in the form of dust from the carbonaceous material within the Feedstock Delivery System ( 2000 ). Particulate solids may be in the form of dust from the carbonaceous material within the Bulk Transfer ( 2 A), Flow Splitting ( 2 B), Mass Flow Regulation ( 2 C), Densification ( 2 D) subsystems of the Feedstock Delivery System ( 2000 ). In embodiments, particulate solids may be ash or char contained within the portion ( 233 ) of the second reactor separated solids ( 232 ) discharged from the second solids separation device ( 250 ) and solids transfer conduit ( 234 ) as shown on  FIG.  26   . A portion ( 233 ) of the second reactor separated solids ( 232 ) from the second solids separation device ( 250 ) and solids transfer conduit ( 234 ) may be routed to the airborne particulate solid evacuation system ( 565 ) as shown on  FIG.  7 C  and  FIG.  26   . 
     The airborne particulate solid evacuation system ( 565 ) is comprised of an entry conduit ( 563 ), a filter ( 566 ), a fan ( 567 ) driven by a motor ( 568 ), and a valve ( 569 ) in fluid communication with a transport unit ( 577 ). The filter ( 566 ) includes an entry section ( 566 A) and an exit section ( 566 B). The particulate solids that enter the filter ( 566 ) are retained within the entry section ( 566 A). Based on size exclusion, the openings of the filter do not permit the particulate solids to pass into from the entry section ( 566 A) to the exit section ( 566 B). A differential pressure sensor ( 571 ) is equipped to measure the pressure difference between the entry section ( 566 A) and an exit section ( 566 B) across the filter ( 566 ).

The particulate solid laden gas ( 572 ) is comprised of a particulate solid portion ( 574 A) and a gas portion ( 574 B). The particulate solid portion ( 574 A) can be dust or particulate solids from the carbonaceous material within the Feedstock Delivery System ( 2000 ). The particulate solid portion ( 574 A) may be combustible. The particulate solids portion ( 574 A) may be ash or char contained within the portion ( 233 ) of the second reactor separated solids ( 232 ) provided from the second solids separation device ( 250 ) and solids transfer conduit ( 234 ) as shown on  FIG.  26   .

     The gas portion ( 574 B) of the of the particulate solid laden gas ( 572 ) is transferred through the filter ( 566 ) from the entry section ( 566 A) to the exit section ( 566 B). The gas portion ( 574 B) is a particulate solid depleted gas ( 573 ) since it has a lesser amount of particulate solids in relation to the particulate solid laden gas ( 572 ) that enters the entry section ( 566 A) of the filter ( 566 ). 
     The particulate solids portion ( 574 A) of the particulate solid laden gas ( 572 ) is retained within the entry section ( 566 A) of the filter ( 566 ). A particulate solid depleted gas ( 573 ) is discharged from the exit section ( 566 B) of the filter ( 566 ) and vented to a safe location. The filtered particulate solids portion ( 574 A) of the particulate solid laden gas ( 572 ) that is retained within the entry section ( 566 A) may be removed via an entry section output ( 576 ) via a valve ( 567 ) and transport unit ( 577 ).

FIG.  10 A  is to be used in conjunction with  FIG.  10    and depicts a listing of valve states that may be used in a variety of methods to operate valves associated with the gas and carbonaceous material mixing system ( 2 G 1 ). 
     It is contemplated that in some embodiments, sequence steps of a gas mixing method may be chosen from any number of states listed in  FIG.  10 A . In embodiments, sequence steps of a gas mixing method may be chosen from a combination of state 1, state 2, and/or state 3, and may incorporate methods or techniques described herein and to be implemented as program instructions and data capable of being stored or conveyed via a computer (COMP). In embodiments, the gas mixing sequence may have only three steps which entail each of those listed in  FIG.  10 A , wherein: step 1 is state 1; step 2 is state 2; and, step 3 is state 3. State  2 G( 1 ) is typically performed at start-up. State  2 G( 2 ) is realized during normal operation. State  2 G( 3 ) is typically performed during shut-down. 
     In state  2 G( 1 ) the first isolation valve (VG 1 ), second isolation valve (VG 2 ), and gas evacuation valve (VG 6 ) are closed. The entry section gas input valve (VG 3 ), middle section gas input valve (VG 4 ), and exit section gas input valve (VG 5 ) are open. The gas evacuation pressure sensor (P-G) is operatively in communication with the gas evacuation valve (VG 6 ) and controller (CG 6 ). The gas evacuation valve (VG 6 ) is set by an operator to a user-defined pressure greater than first reactor pressure (P-A). Undesirable gas ( 2 G- 04 ), such as air, is evacuated from the chamber (G 00 ) by use of a gas ( 2 G- 03 ). Undesirable gas ( 2 G- 04 ), such as air, is purged from the chamber (G 00 ) by use of a first gas supply (G 10 ) transferred through the entry gas connection (G 09 ), into the entry section (G 21 ) of the chamber (G 00 ), and through the evacuation gas connection (G 22 ) and evacuation gas line (G 24 ). 
     In state  2 G( 2 ) the first isolation valve (VG 1 ), second isolation valve (VG 2 ), and exit section gas input valve (VG 5 ) are open. Carbonaceous material ( 2 G- 01 ) is fed to the mixing chamber (G 00 ). A gas ( 2 G- 03 ) is fed to the mixing chamber (G 00 ). The carbonaceous material ( 2 G- 01 ) and gas ( 2 G- 03 ) mix within the mixing chamber (G 00 ) and a carbonaceous material and gas mixture ( 2 G- 02 ) is transferred downstream. It is to be noted that the exit section gas input valve (VG 5 ) is indicated as open in state  2 G( 2 ), however, alternately, the entry section gas input valve (VG 3 ) or middle section gas input valve (VG 4 ) may also be open in addition to the exit section gas input valve (VG 5 ) being open during state  2 G( 2 ). It may in some instances make sense for all three of the entry section gas input valve (VG 3 ), middle section gas input valve (VG 4 ), and exit section gas input valve (VG 5 ), to be open during state  2 G( 2 ) so as to always maintain a positive flow through each one of the entry gas connection (G 09 ), middle gas connection (G 13 ), and exit gas connection (G 15 ) to prevent clogging with carbonaceous material, particulate heat transfer material, volatile reaction products, or SVOC or VOC. 
     In state  2 G( 3 ), the first isolation valve (VG 1 ) and second isolation valve (VG 2 ) are closed. The entry section gas input valve (VG 3 ), middle section gas input valve (VG 4 ), exit section gas input valve (VG 5 ), and gas evacuation valve (VG 6 ) are open. The gas evacuation pressure sensor (P-G) is operatively in communication with the gas evacuation valve (VG 6 ) and controller (CG 6 ). The gas evacuation valve (VG 6 ) is set by an operator to a user-defined pressure greater than first reactor pressure (P-A). Undesirable gas ( 2 G- 04 ), such as product gas, is evacuated from the chamber (G 00 ) by use of a gas ( 2 G- 03 ) such as carbon dioxide or air. Undesirable gas ( 2 G- 04 ), such as product gas, is purged from the chamber (G 00 ) by use of a first gas supply (G 10 ) transferred through the entry gas connection (G 09 ), into the entry section (G 21 ) of the chamber (G 00 ), and through the evacuation gas connection (G 22 ) and evacuation gas line (G 24 ). 
     FIG.  10 B: 
       FIG.  10 B  shows a non-limiting embodiment of a Gas Mixing ( 2 G) method. The following method may be used in conjunction with the content disclosed in  FIG.  10    and  FIG.  10 A . 
     STEP  2 G(A)—Introduce a first gas supply (G 10 ) to the mixing chamber (G 00 ) through an entry gas connection (G 09 ); 
     STEP  2 G(B)—Measure differential pressure between entry section (G 21 ) and exit section (G 19 ) of mixing chamber (G 00 ); 
     STEP  2 G(C)—Compare signal (XDPG) from the differential pressure sensor (DPG) to target set point. If the signal (XDPG) from the differential pressure sensor (DPG) is greater than target set point, go back to step  2 G(A). If the signal (XDPG) from the differential pressure sensor (DPG) is less than or equal to the target set point, then continue to step  2 G:D. In embodiments, the target set point is 5 PSIG which can be inputted to an operator to the computer (COMP). 
     STEP  2 G(D)—Send signal (XG 1 ) to controller (CG 1 ) to open the first isolation valve (VG 1 ) and second isolation valve (VG 2 ); STEP  2 G(E)—Introduce carbonaceous material ( 2 G- 01 ) to mixing chamber (G 00 ); 
     STEP  2 G(F)—Mix carbonaceous material ( 2 G- 01 ) with gas ( 2 C- 03 ) in mixing chamber (G 00 ); 
     STEP  2 G(G)—Introduce carbonaceous material and gas mixture ( 2 G- 02 ) to first reactor ( 100 ); STEP  2 G(H)—Introduce steam, and/or oxygen-containing gas, and/or carbon dioxide to the first reactor ( 100 ); and, 
     STEP  2 G(I)—Generate a first reactor product gas. 
     For example, STEP  2 G(A)—Carbon dioxide is transferred from the carbon dioxide output ( 6 -OUT 2 ) Secondary Gas Clean Up System ( 6000 ) to the gas input ( 2 G-IN 2 A) of the Gas Mixing ( 2 G) subsystem and into the entry section (G 21 ) of the mixing chamber (G 00 ). The first isolation valve (VG 1 ) and second isolation valve (VG 2 ) are both closed. The gas evacuation valve (VG 6 ) is closed. The exit section gas input valve (VG 5 ) is open to purge a third gas supply (G 18 ) through the exit gas connection (G 15 ) and into the exit section (G 19 ) of the chamber (G 00 ) and into the transport assembly ( 2 H 1 ). The middle section gas input valve (VG 4 ) is open to maintain a positive pressure in the middle section (G 20 ) by providing a second gas supply (G 14 ) to the middle gas connection (G 13 ). The entry section gas input valve (VG 3 ) is open to pressurize the entry section (G 21 ) of the chamber (G 00 ). A source of compressed air (D 30 ) may alternately be added to the mixing chamber (G 00 ) through an entry gas connection (G 09 ). 
     The first reactor pressure (P-A) may operate at a pressure within the pressure range of about 9 PSIA to about 75 PSIG. The Secondary Gas Clean Up System ( 6000 ) may operate at a pressure within the pressure range of about 5 PSIG to about 750 PSIG. 
     Any conceivable gas may be used to mix with the carbonaceous material. The claims are not to be construed to expressly limit the mixing gas with any of the gases mentioned in the specification. In embodiments, the mixing gas may be carbon dioxide, air, an oxygen-containing gas, product gas, hydrogen, carbon monoxide, nitrogen, methane, ethane, ethylene, acetylene, propylene, propane, hydrocarbons, VOC, flue gas, biorefinery off-gases, argon, helium, noble gases, natural gas, or the like.

     The entry section (G 21 ) of the mixing chamber (G 00 ) is exposed to a source of pressurized gas ( 2 C- 03 ). The exit section (G 19 ) of the mixing chamber (G 00 ) is exposed to the first reactor ( 100 ) which may operate at a temperature between 570° C. and 1,000° C. (1,058° F. and 1,832° F.). 
     The third gas supply (G 18 ) provided to the exit section (G 19 ) via an exit gas connection (G 15 ) serves to prevent back flow of steam, oxygen-containing gas, carbon dioxide, product gas, or first reactor particulate heat transfer material ( 105 ) to the interior (G 01 ) of the mixing chamber (G 00 ). 
     STEP  2 G(B)—A differential pressure sensor (DPG) measures the difference in pressure of the entry section (G 21 ) and exit section (G 19 ) of the mixing chamber (G 00 ). Pressure from the entry section (G 21 ) of the mixing chamber (G 00 ) is read by the differential pressure sensor (DPG) via an entry impulse line (G 1 A). Pressure from the exit section (G 19 ) of the mixing chamber (G 00 ) is read by the differential pressure sensor (DPG) via an exit impulse line (G 1 B). The differential pressure sensor (DPG) transmits a signal of the pressure difference between the entry section (G 21 ) and the exit section (G 19 ). 
     STEP  2 G(C)—The signal (XDPG) from the differential pressure sensor (DPG) is compared to a target set point. A target set point of 5 PSID. The entry section (G 21 ) of the mixing chamber G 00 ) is being pressurized by a first gas supply (G 10 ). As gas is ( 2 C- 03 ) is transferred to the entry section (G 21 ), the pressure within the interior (G 01 ) of the mixing chamber (G 00 ) increases. A pressure boundary is formed at one end in an upstream densification system ( 2 D 0 ) and at the other end by the surface of the closed first isolation valve (VG 1 ). In case the first isolation valve (VG 1 ) has a leak in it, a pressure boundary is formed at one end in an upstream densification system ( 2 D 0 ) and at the other end by the surface of the closed second isolation valve (VG 2 ). 
     When the signal (XDPG) from the differential pressure sensor (DPG) is greater than target set point continue to introduce a first gas supply (G 10 ) to the mixing chamber (G 00 ) through an entry gas connection (G 09 ). For example, if the signal (XDPG) from the differential pressure sensor (DPG) was 20 PSID then this would be greater than the target set point of 5 PSID and the system would resume introducing a first gas supply (G 10 ) to the mixing chamber (G 00 ). For example, if the signal (XDPG) from the differential pressure sensor (DPG) was 5 PSID then this would be equal to the target set point of 5 PSID and the system may continue on to step  2 G(D). For example, if the signal (XDPG) from the differential pressure sensor (DPG) was 4 PSID then this would be less than the target set point of 5 PSID and the system may continue on to step  2 G(D). 
     STEP  2 G(D)—The computer (COMP) sends a signal (XG 1 , XG 2 ) to controllers (CG 1 , CG 2 ) to open the first isolation valve (VG 1 ) and the second isolation valve (VG 2 ). 
     STEP  2 G(E)—carbonaceous material ( 2 G- 01 ) is introduced to the mixing chamber (G 00 ). There is minimal, if any, but likely no pressure drop signal (XDPG) across the first isolation valve (VG 1 ) and the second isolation valve (VG 1 ). The pressure of the mixing chamber (G 00 ) and the first reactor ( 100 ) are equilibrated. The third gas supply (G 18 ) provided to the exit section (G 19 ) via an exit gas connection (G 15 ) to prevent back flow of carbonaceous material, steam, oxygen-containing gas, carbon dioxide, product gas, or first reactor particulate heat transfer material ( 105 ) to the interior (G 01 ) of the mixing chamber (G 00 ). 
     STEP  2 G(F)—Carbonaceous material ( 2 G- 01 ) is mixed with the gas ( 2 C- 03 ) in mixing chamber (G 00 ). 
     STEP  2 G(G)—The carbonaceous material and gas mixture ( 2 G- 02 ) is transferred to the first reactor ( 100 ) which may operate at a temperature between 570° C. and 1,000° C. (1,058° F. and 1,832° F.). 
     STEP  2 G(H)— Steam, an oxygen-containing gas, and carbon dioxide are introduced into the first reactor ( 100 ); and, 
     STEP  2 G(I)—A first reactor product gas is generated.

       FIG.  11    elaborates upon the non-limiting embodiment of  FIG.  2 A  further including a description of the Transport ( 2 H) subsystem or sequence step of the Feedstock Delivery System ( 2000 ).  FIG.  11    shows one example of a Transport ( 2 H) subsystem accepting a carbonaceous material and gas mixture ( 2 H- 01 ) as an input ( 2 H-IN 1 A) from an output ( 2 G-OUT 1 A) of a Gas Mixing ( 2 G) subsystem. The Transport ( 2 H) subsystem is shown contained within a Transport Control Volume (CV- 2 H). 
     The Transport ( 2 H) subsystem is configured to accept a carbonaceous material and gas mixture ( 2 H- 01 ) and transfer it from the transport input (H 03 ) to the transport output (H 05 ) for delivery to a first reactor ( 100 ) as a carbonaceous material and gas mixture ( 102 A) via an output ( 2 H-OUT 1 A) or a first feed zone delivery system output (FZ-OUT 1 ). The Transport ( 2 H) subsystem includes a transport assembly ( 2 H 1 ) and has a transport assembly first flange (H 02 ) and a transport assembly second flange (H 2 O). The transport assembly first flange (H 02 ) is the transport input (H 03 ). The transport assembly second flange (H 2 O) is the transport output (H 05 ). The transport output (H 05 ) is also the feedstock delivery system output (H 22 ). The transport assembly first flange (H 02 ) is shown connected to the chamber second flange (G 06 ) of the exit section (G 19 ) of the mixing chamber (G 00 ) within the Gas Mixing ( 2 G) subsystem.

     An expansion joint (H 04 ) is interposed in the transport assembly ( 2 H 1 ) between the transport assembly first flange (H 02 ) and the transport assembly second flange (H 2 O). The transport assembly ( 2 H 1 ) has at least one side wall (H 06 ) defining an interior (H 08 ). A screw conveyor (H 10 ) is disposed within the interior (H 08 ) of the transport assembly ( 2 H 1 ).

     It is to be noted that all reference numerals in  FIG.  17    can be applied to the content disclosed in  FIG.  17 A . Each Feedstock Delivery System ( 2000 ,  2000 ′), each First Stage Product Gas Generation System ( 3 A,  3 A′), each Second Stage Product Gas Generation System ( 3 B,  3 B′), and each Third Stage Product Gas Generation System ( 3 C,  3 C′) disclosed in  FIG.  17 A  may include all of the embodiments disclosed in  FIG.  17   . 
     FIG.  17 B: 
       FIG.  17 B  elaborates upon the framework of the entire Biorefinery Superstructure System (BSS) disclosed in  FIG.  17 A  and shows the Primary Gas Clean-Up System ( 4000 ) outputting a primary conditioned syngas (SYN 1 ) and the Secondary Gas Clean-Up System ( 6000 ) outputting a secondary conditioned syngas (SYN 2 ). The secondary conditioned syngas (SYN 2 ) may be used as a fuel ( 110 ,  110 A,  110 B) source in the: plurality of First Stage Product Gas Generation Systems ( 3 A,  3 A′) contained within plurality of the First Stage Product Gas Generation Control Volumes (CV- 3 A, CV- 3 A′); and the plurality of Third Stage Product Gas Generation Systems ( 3 C,  3 C′) contained within plurality of the Third Stage Product Gas Generation Control Volumes (CV- 3 C, CV- 3 C′). Alternatively, or additionally, the primary conditioned syngas (SYN 1 ) may be used as the fuel ( 110 ,  110 A,  110 B), as depicted by the laterally extending broken arrow in  FIG.  17 B . 
     Thus, in some embodiments, a conditioned syngas (i.e., a syngas that has been subject to processing to remove one or more undesirable substances therefrom) is recycled and introduced into (1) the first reactor heat exchangers (HX-A, HX-A′) which are in thermal contact with the First Stage Product Gas Generation Systems ( 3 A,  3 A′) to provide the energy to endothermically react the carbonaceous material ( 500 ); and (2) the Third Stage Product Gas Generation Systems ( 3 C,  3 C′) for use in the combustion zone (CZ-A) and/or the reaction zone (CZ-B) for use as the first hydrocarbon stream ( 322 ) and/or the second hydrocarbon stream input ( 328 ) (as depicted in  FIG.  32   ). Thus, at least a portion of conditioned syngas, produced during the clean-up process, is recycled to help make additional syngas. This is especially advantageous in those instances where other combustible gases, such as natural gas, are not available as an input gas to the pulse combustion units and the combustion zones (CZ-A), and/or the reaction zone (CZ-B). 
     As discussed further below with respect to  FIG.  17 C , additional products, such as tail gas, naphtha, and first and second off-gases may also be transferred, for use as a fuel, to the first reactor heat exchangers (HX-A, HX-A′) of the First Stage Product Gas Generation Systems and/or to the Third Stage Product Gas Generation Systems (i.e. the hydrocarbon reformers). 
     As seen in  FIG.  17 B , the recycled secondary and/or primary conditioned syngas (SYN 2 , SYN 1 ) is split into a plurality of recycled syngas streams (SYN 3 , SYN 4 , SYN 5 , SYN 6 ). Of these, a first set of recycled syngas streams (SYN 3 , SYN 4 ) may be transferred to the first reactor heat exchangers (HX-A, HX-A′) to drive the pulse combustion devices, while a second set of recycled syngas streams (SYN 5 , STN 6 ) may be transferred to the Third Stage Product Gas Generation Systems ( 3 C,  3 C′) for use in the combustion zone (CZ-A) and/or the reaction zone (CZ-B).

Any type of heat exchanger may be used, such as pulse heater tailpipes, electrical heater rods in thermowells, fuel cells, heat pipes, fire-tubes, annulus-type heat exchangers, or radiant tubes. The embodiment of  FIG.  18    also shows the heat of reaction also being supplied to the particulate heat transfer material ( 105 ) of the first reactor ( 100 ) directly by utilization of a fuel ( 3 A-IN 4 ) such as a mixture of hydrocarbons and an oxygen-containing gas. A portion of the product gas may be supplied as fuel ( 110 ) to the pulse combustion devices and combustion of these gases provides the heat necessary for the indirect endothermic thermochemical processes taking place within the first interior ( 101 ) of the first reactor ( 100 ). In one embodiment, the heat exchangers (HX-A 1 , HX-A 3 ) may be a pulse combustion device that combusts a source of fuel ( 110 ) to form a pulse combustion stream ( 114 ) comprising flue gas. The pulse combustion stream ( 114 ) indirectly heats the particulate heat transfer material ( 105 ) of the first reactor ( 100 ). As used therein, indirectly heating the bed means that the pulse combustion stream ( 114 ) does not contact the contents of the bed material ( 105 ) of the first reactor ( 100 ). 
     In some embodiments, the combustion of the fuel and oxygen-containing gas contained in the first reactor heat exchanger fuel ( 110 ) takes place within the first reactor heat exchangers (HX-A 1 , HX-A 3 ). As a result, the first reactor heat exchanger fuel inlet temperature (T 3 ) will be less than the first reactor heat exchanger combined combustion stream outlet temperature (T 4 ). In some embodiments, the combustion of the fuel and oxygen-containing gas contained in the first reactor heat exchanger fuel ( 110 ) takes place outside of and prior to entering the first reactor heat exchangers (HX-A 1 , HX-A 3 ). As a result, the first reactor heat exchanger combined combustion stream outlet temperature (T 4 ) will be less than the first reactor heat exchanger fuel inlet temperature (T 3 ). Heat exchangers for transferring thermal energy to a particulate heat transfer material ( 105 ) contained within the interior ( 101 ) of a first reactor are well known in the art and as such the details and design are not particularly relevant here. 
     In embodiments, the first reactor particulate heat transfer material ( 105 ) is comprised of Geldart Group A or Group B solids in the form of inert material or catalyst or sorbent or engineered particles. The engineered particles may be made of alumina, zirconia, sand, olivine sand, limestone, dolomite, or catalytic materials, any of which may be hollow in form, such as microballoons or microspheres. The preferred first reactor particulate heat transfer material ( 105 ) is Geldart Group B alumina microballons.

Thus when MSW and/or RDF are transferred to the first reactor ( 100 ), inert feedstock contaminants contained therein, are also unavoidably transferred to the first reactor ( 100 ) as well. 
     The inert feedstock contaminant portion of the MSW within the carbonaceous material and gas mixture ( 102 ) of  FIG.  24    is that which cannot be converted into a product gas ( 122 ) and as a result, accumulates within the interior ( 101 ) of the first reactor ( 100 ). It is therefore desirable to be able to remove Geldart Group D inert feedstock contaminant solids which may accumulate within the first reactor ( 100 ). Thus it is therefore desirable to be able to clean bed material by classification or via the removal of Geldart Group D inert feedstock contaminant solids therefrom to permit continuous and uninterrupted operation within the first reactor ( 100 ). 
     The accumulation of Geldart Group D inert feedstock contaminant solids within the first reactor ( 100 ) inhibits continuous operation of the first reactor ( 100 ) and may cause defluidization within the first reactor ( 100 ). Defluidization of the first reactor ( 100 ) may be caused by unpredictable and unavoidable buildup of larger Geldart particles, in comparison to the mean bed particle characteristic, introduced to the interior ( 101 ). For example,  FIG.  24    depicts an interior ( 101 ) comprised of a fluidized bed of a mean bed particle characteristic of Geldart Group B solids which may become defluidized by buildup or accumulation of comparatively larger, coarser and/or heavier Geldart Group D solids that are introduced to the fluidized bed with the carbonaceous material ( 102 ). 
     A mixture transfer valve (V 9 , V 9 A, V 9 AA) is interposed in each mixture transfer conduit (A 3 A, A 3 AA) in between the first reactor ( 100 ) and each particulate classification chamber (A 1 A, A 1 B) to start and stop flow of the contents transferred therein, and to isolate the particulate classification chamber (A 1 A, A 1 B) from the first reactor ( 100 ). 
     Each particulate classification chamber (A 1 A, A 1 B) is equipped with a classifier gas input (A 6 A, A 6 AA) configured to introduce a classifier gas (A 16 , A 16 A) to each interior (IN 1 , INB). The classifier gas input (A 6 A, A 6 AA) may carbon dioxide provided from the carbon dioxide output ( 6 -OUT 2 ) of a downstream Secondary Gas Clean-Up System ( 6000 ) as seen in  FIGS.  16  and  17   . The classifier gas (A 16 , A 16 A) is preferably carbon dioxide. However, the classifier gas (A 16 , A 16 A) may be any gas as deemed appropriate, such as nitrogen, product gas, air, hydrocarbons, biorefinery off-gases, or the like. 
     A classification gas transfer valve (V 10 , V 10 A, V 10 AA) is configured to regulate classifier gas (A 16 , A 16 A) flow through the classifier gas input (A 6 A, A 6 AA) to the interior (INA, INB) of the particulate classification chamber (A 1 A, A 1 B). Each particulate classification chamber (A 1 A, A 1 B) is equipped with a classified recycled bed material output (A 7 A, A 7 AA) in fluid communication with the interior ( 101 ) of the first reactor ( 100 ) via a classified recycled bed material input (A 27 , A 27 A) and a classifier riser (A 17 , A 17 A). 
     The classified recycled bed material input (A 27 , A 27 A) is preferably positioned at or above the fluid bed level (L-A) of the first reactor ( 100 ) so as to let the recycled bed material or particulate heat transfer material ( 105 ) to be recycled back to the interior ( 101 ) of the first reactor ( 100 ) in an unimpeded manner. 
     A bed material riser recycle transfer valve (V 11 , V 11 A, V 11 AA) is interposed in each classifier riser (A 17 , A 17 A) in between the first reactor ( 100 ) and each particulate classification chamber (A 1 A, A 1 B) to start and stop flow of the contents transferred therein, and to isolate the particulate classification chamber (A 1 A, A 1 B) from the first reactor ( 100 ). 
     Each particulate classification chamber (A 1 A, A 1 B) is equipped with a classifier inert feedstock contaminant output (A 9 A, A 9 AA) configured to remove classified inert feedstock contaminants (A 19 , A 19 A) from the interior (INA, INB). 
     An inert feedstock contaminant drain valve (V 13 , V 13 A, V 13 AA) is configured to start and stop flow of classified inert feedstock contaminants (A 19 , A 19 A) transferring through the classifier inert feedstock contaminant output (A 9 A, A 9 AA). 
     Each particulate classification chamber (A 1 A, A 1 B) may also be equipped with a classifier depressurization gas output (A 8 A, A 8 AA) configured to evacuate classifier depressurization gas (A 18 , A 18 A) from the interior (INA, INB) thus reducing the pressure contained therein. 
     A depressurization vent valve (V 12 , V 12 A, V 12 AA) is configured to start and stop flow of classifier depressurization gas (A 18 , A 18 A) transferred through the classifier depressurization gas output (A 8 A, A 8 AA). 
     The classified recycled bed material output (A 7 A, A 7 AA) is configured to output a classified recycled bed material (A 37 , A 37 A) to the interior ( 101 ) of the first reactor ( 100 ). In embodiments, the classifier riser (A 17 , A 17 A) conveys the classified recycled bed material (A 37 , A 37 A) to the interior ( 101 ) of the first reactor ( 100 ) in a suspension of gas (A 16 , A 16 A) and conveyed in a dilute-phase flow regime. 
     A first reactor mixture input ( 3 A-IN 1 A) and a second reactor mixture input ( 3 A-IN 1 B) are introduced to the feed zone (AZ-B) of the first reactor ( 100 ) as a first carbonaceous material and gas mixture ( 102 A) and a second carbonaceous material and gas mixture ( 102 B). The first carbonaceous material and gas mixture ( 102 A) and a second carbonaceous material and gas mixture ( 102 B) are introduced to the interior ( 101 ) of the first reactor ( 100 ) for intimate contact with the heated particulate heat transfer material ( 105 ), reactants ( 106 ,  106 A,  106 B,  106 C) and oxygen-containing gas ( 118 ,  118   a ,  118 B,  118 C) contained within the interior ( 101 ) to produce a first reactor product gas ( 122 ) that is discharged from the interior ( 101 ) of the first reactor ( 100 ) via a first reactor product gas output ( 124 ). The first reactor product gas ( 122 ) includes first syngas comprising carbon monoxide and hydrogen. It also includes char, volatiles and other gases. 
       FIG.  24    is to be used in conjunction with  FIG.  25    which depicts a valve sequencing diagram that describes the method of operating the sequence of the product gas generation and particulate classification system ( 1002 ) embodiment shown in  FIG.  24   . 
       FIG.  24    shows one embodiment of the product gas generation and particulate classification system ( 1002 ) equipped with a variety of sensors, valves, assets and controllers which are all configured to methodically and systematically manipulate the operation of the particulate classification chamber (A 1 A, A 1 B) to accept a variety of inputs and discharge a variety of outputs to and from the first reactor ( 100 ). 
     The particulate classification chamber (A 1 A, A 1 B) is configured to accept the bed material and inert feedstock contaminant mixture (A 4 A, A 4 AA) transferred from the interior ( 101 ) of the first reactor ( 100 ). In embodiments, the bed material and inert feedstock contaminant mixture (A 4 A, A 4 AA) are conveyed in a dense phase flow regime through the mixture transfer conduit (A 3 A, A 3 AA) into the classifier interior (INA, INB). The bed material and inert feedstock contaminant mixture (A 4 A, A 4 AA) is comprised of a bed material portion and an inert feedstock contaminant portion. The bed material and inert feedstock contaminant mixture (A 4 A, A 4 AA) is transferred to the classifier interior (INA, INB) via a mixture transfer conduit (A 3 A, A 3 AA) and flow is regulated through modulation or actuation of an associated mixture transfer valve (V 9 A, V 9 AA). 
     In embodiments,  FIG.  24    shows the first reactor ( 100 ) having particulate heat transfer material ( 105 ) with a mean bed particle characteristic including Geldart Group B solids. Therefore, the bed material portion of the mixture (A 4 A, A 4 AA) is comprised of Geldart Group B solids and the inert feedstock contaminant portion is comprised of Geldart Group D solids. The embodiment of  FIG.  24    shows the classification chamber (A 1 A, A 1 B) configured to accept a classifier gas (A 16 , A 16 A), such as carbon dioxide, the supply of which is regulated through modulation or actuation of a classification gas transfer valve (V 10 A, V 10 AA). 
     In response to accepting the gas (A 16 , A 16 A), the classification chamber (A 1 A, A 1 B) is configured to output: (1) a bed material portion to be returned to the first reactor ( 100 ); and, (2) an inert feedstock contaminant portion to be discharged from the classifier chamber (A 1 A, A 1 B). As a result, the bed material and inert feedstock contaminant mixture (A 4 A, A 4 AA) is cleaned to separate the bed material portion (Geldart Group B solids) from the inert feedstock contaminant portion (Geldart Group D solids). The cleaned and separated bed material portion (Geldart Group B solids) is then available to be used again in the first reactor ( 100 ) in a thermochemical process to generate a product gas. 
     The system in  FIG.  24    displays a first reactor ( 100 ) configured to accept a carbonaceous material and gas mixture ( 102 A,  102 B), such as MSW containing inert feedstock contaminants. The system in  FIG.  24    also displays a first reactor ( 100 ) configured to accept a first reactor reactant input ( 3 A-IN 2 A) or the second reactor heat transfer medium output ( 3 B-OUT 2 ), such as steam, from the third reactor heat exchanger (HX-C) (not shown). The system in  FIG.  24    also displays a first reactor ( 100 ) configured to accept an oxygen-containing gas ( 118 ) through an input ( 3 A-IN 3 ). 
       FIG.  16    and  FIG.  17    display a Biorefinery Superstructure System (BSS) equipped with a Secondary Gas Clean-Up System ( 6000 ) configured to remove carbon dioxide from product gas. The Secondary Gas Clean-Up System ( 6000 ) has a secondary gas clean-up input ( 6 -IN 1 ) and a secondary gas clean-up system output ( 6 -OUT 1 ). Membrane based carbon dioxide removal systems and processes are preferred to remove carbon dioxide from product gas, however other alternate systems and methods may be utilized to remove carbon dioxide, not limited to adsorption or absorption based carbon dioxide removal systems and processes. 
       FIG.  16    and  FIG.  17    display the Secondary Gas Clean-Up System ( 6000 ) discharging carbon dioxide via a carbon dioxide output ( 6 -OUT 2 ) to both the (1) First Stage Product Gas Generation System ( 3 A), for use as a classifier gas (A 16 , A 16 A), and to the (2) the Feedstock Delivery System ( 2000 ) to be combined with a carbonaceous material ( 500 ). Thus  FIG.  24    displays the product gas generation and particulate classification system ( 1002 ) in the context of a Biorefinery Superstructure System (BSS) as depicted in  FIG.  16    and  FIG.  17    and displays the introduction of the combined carbonaceous material and carbon dioxide into a first reactor via a reactor mixture input ( 3 A-IN 1 ). 
     Thus  FIG.  24    depicts the system ( 1002 ) configured to react the MSW carbonaceous material with steam, carbon dioxide, and an oxygen-containing gas in a thermochemical process to generate a first reactor product gas containing char. For example, in embodiments, the first reactor ( 100 ) in  FIG.  24    operates under a combination of steam reforming, water-gas shift, dry reforming, and partial oxidation thermochemical processes.  FIG.  24    also shows combustion taking place within the first reactor first heat exchangers (HX-A 1 , HX-A 2 , HX-A 3 , HX-A 4 ) to indirectly heat the first reactor particulate heat transfer material ( 105 ) contained within the first reactor ( 100 ). The first reactor particulate heat transfer material ( 105 ) essentially is a bed material and inert feedstock contaminant mixture due to the introduction of MSW introduced to the reactor that contains inert feedstock contaminants that build up within the interior ( 101 ) of the first reactor ( 100 ). 
     The product gas shown generated in  FIG.  24    contains carbon dioxide, which is then later separated out in the Secondary Gas Clean-Up System ( 6000 ) to allow the carbon dioxide to be recycled back to the (1) Feedstock Delivery System ( 2000 ) to be combined with a carbonaceous material for transfer to the first reactor ( 100 ), and the (2) First Stage Product Gas Generation System ( 3 A) for use as a classifier gas (A 16 , A 16 A) to clean the bed material. Thus the first particulate heat transfer material may be cleaned with a gas, or a portion of the product gas generated in the first reactor ( 100 ), such as for example, the carbon dioxide portion of the product gas generated in the first reactor that is recycled from a downstream Secondary Gas Clean-Up System ( 6000 ). 
     The embodiment of  FIG.  24    shows the bed material portion comprised of Geldart Group A or B solids free of inert contaminants, transferred and regulated through actuation or modulation of a bed material riser recycle transfer valve (V 11 A, V 11 AA) that is positioned on a classifier riser (A 17 , A 17 A). 
     The embodiment of  FIG.  24    also shows the classification chamber (A 1 A, A 1 B) configured to transfer Geldart Group D solids free of Geldart Group A or B solids as an inert feedstock contaminant portion from the classifier chamber (A 1 A, A 1 B) for removal from the via an inert feedstock contaminant drain valve (V 13 A, V 13 AA) positioned on the classifier inert feedstock contaminant output (A 9 A, A 9 AA). 
     A depressurization vent valve (V 12 A, V 12 AA) may optionally be utilized to evacuate residual pressured gas from the contents of the classification chamber (A 1 A, A 1 B) to prevent erosion and solids abrasion of solids passing through the inert feedstock contaminant drain valve (V 13 A, V 13 AA). 
     In embodiments,  FIG.  24    depicts a municipal solid waste (MSW) energy recovery system for converting MSW containing inert feedstock contaminants, into a product gas ( 122 ), the system comprising:
         (a) a first splitter ( 2 B 1 ) in fluid communication with a first feed zone delivery system ( 2050 A) and a second feed zone delivery system ( 2050 B);   (b) a first feed zone delivery system ( 2050 A) as seen in  FIG.  14    wherein the first feed zone delivery system ( 2050 A) includes at least a Gas Mixing ( 2 G) subsystem and a Transport ( 2 H) subsystem of  FIG.  2 E ;   (c) a second feed zone delivery system ( 2050 B) as seen in  FIG.  14    wherein the second feed zone delivery system ( 2050 B) includes at least Gas Mixing ( 2 G) subsystem and a Transport ( 2 H) subsystem of  FIG.  2 E ;   (d) a first reactor ( 100 ) comprising: a first reactor interior ( 101 ) suitable for accommodating a bed material and endothermically reacting MSW in the presence of steam to produce product gas; a first carbonaceous material and gas input ( 104 A) provided by a first feed zone delivery system ( 2050 A) and configured to input a first carbonaceous material and gas mixture ( 102 A) to the first interior ( 101 ) of the first reactor ( 100 ); a second carbonaceous material and gas input ( 104 B) provided by a second feed zone delivery system ( 2050 B) and configured to input a second carbonaceous material and gas mixture ( 102 B) to the first interior ( 101 ) of the first reactor ( 100 );   (e) a first reactor reactant input ( 108 A,  108 B,  108 C) for introducing steam into the first interior ( 101 ); a first reactor product gas output ( 124 ) through which product gas is removed; a classified recycled bed material input (A 27 , A 27 A) in fluid communication with an upper portion of the first reactor interior ( 101 ); a particulate output (A 2 A, A 2 AA) connected to a lower portion of the first reactor interior, and through which a mixture (A 4 A, A 4 AA) of bed material and unreacted inert feedstock contaminants selectively exits the first reactor interior; and   (f) a plurality of particulate classification chambers (A 1 A, A 1 B) in fluid communication with the first reactor interior ( 101 ), each chamber comprising:   (i) a mixture input (A 5 A, A 5 AA) connected to the particulate output (A 2 A, A 2 AA), for receiving said mixture from the first reactor interior ( 101 );   (ii) a classifier gas input (A 6 A, A 6 AA) connected to a source of classifier gas (A 16 , A 16 A), for receiving classifier gas to promote separation of said bed material from said unreacted inert feedstock contaminants within said chamber;   (iii) a bed material output (A 7 A, A 7 AA) connected to the classified recycled bed material input (A 27 , A 27 A) of the first reactor interior ( 101 ) via a classifier riser conduit (A 17 , A 17 A), for returning bed material separated from said mixture to the first reactor interior; and   (iv) a contaminant output (A 9 A, A 9 AA) for removing unreacted inert feedstock contaminants (A 19 , A 19 A) which have been separated from said mixture, within the chamber.       

     In embodiments,  FIG.  24    discloses a mixture transfer valve (V 9 A, V 9 AA) positioned between the particulate output (A 2 A, A 2 AA) and the mixture input (A 5 A, A 5 AA), to selectively control transfer of said mixture from the first reactor to the chamber; a classification gas transfer valve (V 10 A, V 10 AA) positioned between the source of classifier gas (A 16 , A 16 A) and the classifier gas input (A 6 A, A 6 AA), to selectively provide said classifier gas to the chamber; a bed material riser recycle transfer valve (V 11 A, V 11 AA) positioned between the bed material output (A 7 A, A 7 AA) and the classified recycled bed material input (A 27 , A 27 A), to selectively return bed material separated from said mixture, to the first reactor interior; and an inert feedstock contaminant drain valve (V 13 A, V 13 AA) configured to selectively remove unreacted inert feedstock contaminants (A 19 , A 19 A) which have been separated from said mixture. In embodiments, each chamber further comprises a classifier depressurization gas output (A 8 A, A 8 AA) and a depressurization vent valve (V 12 A, V 12 AA) connected to the classifier depressurization gas output (A 8 A, A 8 AA) to selectively vent the chamber. 
     In embodiments,  FIG.  24    depicts a computer (COMP) configured to operate the system in any one of a plurality of states disclosed in  FIG.  25   , including: a first state in which all of said valves are closed; a second state in which the mixture transfer valve (V 9 A, V 9 AA) is open and the remainder of said valves are closed, to allow said mixture to enter the chamber; a third state in which the classification gas transfer valve (V 10 A, V 10 AA) and the bed material riser recycle transfer valve (V 11 A, V 11 AA) are open and the remainder of said valves are closed, to promote separation of said bed material from said mixture and recycling of separated bed material back into the first reactor; a fourth state in which the depressurization vent valve (V 12 A, V 12 AA) is open and the remainder of said valves are closed, to allow the chamber to vent; and a fifth state in which the inert feedstock contaminant drain valve (V 13 A, V 13 AA) is open and the remainder of said valves are closed, to remove unreacted inert feedstock contaminants from the chamber. In embodiments, the classifier gas may be carbon dioxide.

In embodiments, the first reactor operates at any combination or permutation of thermochemical processes or reactions identified above. In embodiments, the first reactor is operated at a temperature between 500° C. and about 1400° C. to exothermically react the MSW in the presence of an oxygen-containing gas to produce product gas. In embodiments, the first reactor operates at any combination or permutation of thermochemical processes or reactions identified above. 
     FIG.  25 : 
       FIG.  25    depicts the Classification Valve States for Automated Controller Operation of a typical particulate classification procedure.  FIG.  25    is to be used in conjunction with  FIG.  24    and depicts a listing of valve states that may be used in a variety of methods to operate valves associated with the particulate classification chambers (A 1 A, A 1 B).  FIG.  25    identifies five separate discrete valve states of which any number of states can be selected to result in a sequence of steps for the classification of bed material and recovery of inert feedstock contaminants to prevent defluidization within the first reactor ( 100 ). 
     In embodiments, methods may be implemented for operating the product gas generation and classification system depicted in  FIG.  24    by using the discrete states listed in  FIG.  25    to realize a sequence of steps.  FIG.  24    depicts a computer (COMP) that is configured to communicate and cooperate with controllers and valves associated with the particulate classification chambers (A 1 A, A 1 B). The computer (COMP) may be configured to operate the system using any combinations and permutations of states listed in  FIG.  25   . 
     It is contemplated that in some embodiments, sequence steps of a classification method may be chosen from any number of states listed in  FIG.  25   . In embodiments, sequence steps of a classification method may be chosen from a combination of state 1, state 2, state 3, state 4, and/or state 5, and may incorporate methods or techniques described herein and to be implemented as program instructions and data capable of being stored or conveyed via a master controller. In embodiments, the classification sequence may have only five steps which entail each of those listed in  FIG.  25   , wherein: step 1 is state 1; step 2 is state 2; step 3 is state 3; step 4 is state 4; and, step 5 is state 5. This may be typical if a carbonaceous material comprising MSW is fed into the first reactor that has a relatively greater than average amount of inert feedstock contaminants, where states 1 through 3 are not repeated because a sufficient quantity of inert feedstock contaminants is sufficiently present within the classifier prior to proceeding with state 4 and state 5 to vent and drain the classifier, respectively. 
     In embodiments, state 1, state 2, and state 3 may be repeated at least once prior to implementing state 4 and state 5. For example, the classification sequence may have eight steps, wherein states 1 through 3 are repeated once prior to proceeding with state 4 and state 5, wherein: step 1 is state 1; step 2 is state 2; step 3 is state 3; step 4 is state 1; and step 5 is state 2; step 6 is state 3; step 7 is state 4; and, step 8 is state 5. Thus, a classification sequence may entail a multitude of different combinations and permutations of sequence steps given the operator or user defined states to be repeated. For example, from a practical perspective, if a carbonaceous material comprising MSW is fed into the first reactor that has a relatively minimal amount of inert feedstock contaminants, states 1 through 3 may be repeated at least once, or several times, to ensure that a sufficient quantity of inert feedstock contaminants is present within the classifier vessel prior to proceeding with states 4 and state 5 to vent and drain the classifier, respectively. 
     Nonetheless, any combination or permutation of classifier method states and steps may be selected by a user or operator to realize the goal of cleaning the first particulate heat transfer material with a gas, such as carbon dioxide recycled from a downstream Secondary Gas Clean-Up System ( 6000 ), in a systematic, logical, and directed manner. The objective of the classifier (A 1 A) is to achieve 99% separation of the bed material portion from the inert feedstock contaminant portion in the classification state 3. 
     Disclosed methods or techniques may include the execution and implementation of states associated with the Automated Controller Operated Classification Valve Sequence Matrix as depicted in  FIG.  25   . Embodiments of the sequencing methods including steps and states may be implemented by program instructions entered into the computer (COMP) by a user or operator via an input/output interface (I/O) as disclosed in  FIG.  24   . Program and sequencing instructions may be executed to perform a particular computational functions such as automated operation of the valves associated with the product gas generation and classification system as depicted in  FIG.  24   . 
     The following describes various further embodiments of the systems and methods discussed above, and presents exemplary techniques and uses illustrating variations. Thus, the computer (COMP) may implement automation of the following controllers and their respective valves: mixture transfer valve controller (C 9 A, C 9 AA); classification gas transfer valve controller (C 10 A, C 10 AA); bed material riser recycle transfer valve controller (C 11 A, C 11 AA); depressurization vent valve controller (C 12 A, C 12 AA); and, inert feedstock contaminant drain valve controller (C 13 A, C 13 AA). 
     Controllers are shown only on the first of two shown particulate classification vessels (A 1 A) for simplicity in  FIG.  24   . However, it is to be noted that each valve depicted in  FIG.  24    has an associated controller that acts in communication with the computer (COMP). 
     FIG.  26 : 
       FIG.  26    is a detailed view showing a non-limiting embodiment of a Second Stage Product Gas Generation Control Volume (CV- 3 B) and Second Stage Product Gas Generation System ( 3 B) of a three-stage energy-integrated product gas generation system ( 1001 ) including a second reactor ( 200 ) equipped with a dense bed zone (BZ-A), feed zone (BZ-B), and splash zone (BZ-C), along with a second reactor heat exchanger (HX-B), first solids separation device ( 150 ), second solids separation device ( 250 ), solids flow regulator ( 245 ), riser ( 236 ), dipleg ( 244 ), and valves, sensors, and controllers. 
       FIG.  26    shows a second reactor ( 200 ) having a second interior ( 201 ) provided with a dense bed zone (BZ-A), a feed zone (BZ-B) above the dense bed zone (BZ-A), and a splash zone (BZ-C) above the feed zone (BZ-B).

In embodiments, a superstoichiometric amount of oxygen is provided to the combustion zone (CZ-A) so that when all of the hydrocarbon stream ( 322 ) is burned, there is still excess oxygen-containing gas ( 318 ) left over. 
     The combustion zone (CZ-A) accepts a third reactor oxygen-containing gas ( 318 ) through a third reactor oxygen-containing gas input ( 320 ) or an oxygen-containing gas input ( 3 C-IN 3 ). The combustion zone (CZ-A) also accepts a first hydrocarbon stream ( 322 ) through a first hydrocarbon stream input ( 324 ) or a first hydrocarbon input ( 3 C-IN 4 ). In embodiments, the first hydrocarbon input ( 3 C-IN 4 ) to the Third Stage Product Gas Generation System ( 3 C) may be a first synthesis hydrocarbon output ( 7 -OUT 2 ) such as Fischer Tropsch tail gas transferred from a downstream Synthesis System ( 7000 ). In other embodiments, the first hydrocarbon stream ( 322 ) may be natural gas, or naphtha, or off-gas from a downstream Upgrading System ( 8000 ). The first hydrocarbon stream ( 322 ), in some instances, may be product gas, or even landfill gas including a complex mix of different gases created by the action of microorganisms within a landfill. 
     A first hydrocarbon valve (VC 1 ) may be configured to regulate the flow of the first hydrocarbon stream ( 322 ) to the first hydrocarbon stream input ( 324 ). The first hydrocarbon valve (VC 1 ) has a controller (CC 1 ) configured to input or output a signal (XC 1 ). A third reactor oxygen-containing gas valve (VC 2 ) may be configured to regulate the flow of the third reactor oxygen-containing gas ( 318 ) through the third reactor oxygen-containing gas input ( 320 ). The third reactor oxygen-containing gas valve (VC 2 ) has a controller (CC 2 ) configured to input or output a signal (XC 2 ). 
     A second hydrocarbon valve (VC 3 ) may be configured to regulate the flow of the second hydrocarbon stream ( 326 ) to the second hydrocarbon stream input ( 328 ). The second hydrocarbon valve (VC 3 ) has a controller (CC 3 ) configured to input or output a signal (XC 3 ). A third hydrocarbon valve (VC 4 ) may be configured to regulate the flow of the third hydrocarbon stream ( 330 ) to the third hydrocarbon stream input ( 332 ). The third hydrocarbon valve (VC 4 ) has a controller (CC 4 ) configured to input or output a signal (XC 4 ). A third reactor heat transfer medium valve (VC 5 ) may be configured to regulate the flow of the third reactor heat transfer medium ( 310 ) to the steam drum ( 350 ). The third reactor heat transfer medium valve (VC 5 ) has a controller (CC 5 ) configured to input or output a signal (XC 5 ). 
     An oxygen-containing gas ( 318 ) is provided to the third reactor ( 300 ) so that the hydrocarbon ( 322 ) is reacted at an elevated reaction temperature sufficient to convert the hydrocarbon ( 322 ) substantially completely into carbon dioxide. Therefore, a combustion zone output (CZ-AP) includes carbon dioxide, heat, and left over oxygen-containing gas ( 318 ), and is discharged from the combustion zone (CZ-A) to the reaction zone (CZ-B) of the third reactor ( 300 ). A sufficient oxygen-containing gas ( 318 ) is provided to the third reactor ( 300 ) so that excess oxygen-containing gas ( 318 ) remains unreacted and exits the burner ( 346 ) and thus is also present in the combustion stream discharged from the combustion zone (CZ-A). 
     In embodiments, an annulus type burner may be employed to react the first hydrocarbon stream ( 322 ) with the third reactor oxygen-containing gas ( 318 ) through the thermochemical process of combustion. In embodiments, the burner ( 346 ) is a multi-orifice, co-annular, burner provided with an arrangement of several passages coaxial with the longitudinal axis of the burner. Multi-orifice burners comprising arrangements of annular concentric channels for reacting an oxygen-containing gas ( 318 ) with a stream of hydrocarbons ( 322 ) may, in some instances, have a reduced area to permit a high velocity stream to take place and result in very rapid and complete reaction of the combustion stream (CZ-A) with the combined product gas ( 302 ) introduced to the third reactor ( 300 ) to form a reaction stream. The design of the burner ( 346 ) is not particularly relevant. Various types of burners may be used. Preferably, a burner is selected that is configured to react a combustible hydrocarbon stream ( 322 ) with a stream of oxygen-containing gas ( 318 ). The burner may be equipped with an ignitor. 
     In embodiments, the burner ( 346 ) is that of an annulus type. In embodiments, the burner ( 346 ) may be of the type configured to accept a hydrocarbon stream ( 322 ) and oxygen-containing gas stream ( 318 ) through concentric ports, wherein the oxygen-containing gas ( 318 ) is injected into an annular port, and the hydrocarbon stream ( 322 ) is injected to the central port. The burner ( 346 ) ensures rapid and intimate mixing and combustion of the hydrocarbon ( 322 ) with the oxygen-containing gas ( 318 ). The hydrocarbon stream ( 322 ) and oxygen-containing gas ( 318 ) are introduced under pressure and combustion of the hydrocarbon ( 322 ) is completed in the burner ( 346 ) and terminates at the burner nozzle ( 347 ). In embodiments, the burner is constructed such that the reaction between the hydrocarbon ( 322 ) and the oxygen-containing gas ( 318 ) takes place entirely outside the burner ( 346 ) and only at the burner nozzle ( 347 ) so as to provide protection of the burner ( 346 ) from overheating and from direct oxidation. In embodiments, the burner ( 346 ) or the burner nozzle ( 347 ) is equipped with a cooling water circuit (not shown). 
     In embodiments, the burner nozzle ( 347 ) may be defined by a restriction constituting a reduction in area to provide an increase in velocity of the combustion stream (CZ-AP) exiting the burner nozzle ( 347 ). The restriction may even be in some instances a baffle or an impingement plate on which the flame of the combustion stream is stabilized. The burner nozzle ( 347 ) may have a restricting or constricting throat zone, or orifice to accelerate velocity of the combustion stream (CZ-AP) in the transition from the combustion zone (CZ-A) to the reaction zone (CZ-B). A restriction, orifice, baffle, or impingement surface is advantageous to shield the combustion zone (CZ-A) from pressure fluctuations of the reaction zone (CZ-B) to mediate operational difficulties such as burner oscillation, flash-back, detonation, and blow-out. 
     In some embodiments, combustion stream (CZ-AP) exiting the burner nozzle ( 347 ) may be transferred at velocities within the range of 200 feet per minute (ft/m) to the speed of sound under the existing conditions. But advantageously the combustion stream (CZ-AP) that is discharged from the combustion zone (CZ-A), via the burner nozzle ( 347 ), is at a velocity between 50 and 300 feet per second (ft/s) and typically less than 200 ft/s. 
     The combined product gas ( 302 ) must not be allowed to remain at high temperatures for more than a fraction of a second, or more than a few seconds, the critical reaction period limits being about 0.0001 second to about 5 seconds. Normally it is advantageous to maintain reaction time between the combined product gas ( 302 ) and combustion stream (CZ-AP) of 0.1 to 5.0 seconds to sufficiently completely partially oxidize SVOC, VOC, and char into additional hydrogen and carbon monoxide. Preferably the residence time of the combined product gas ( 302 ) and combustion stream (CZ-AP) in the reaction zone is about 3 seconds. 
     The combustion zone output (CZ-AP) is discharged from the combustion zone (CZ-A) to the reaction zone (CZ-B). The combustion stream is comprised of an intensely hot mixture of carbon dioxide and excess oxygen-containing gas. The heat generated between the combustion of the hydrocarbon ( 322 ) with the oxygen-containing gas ( 318 ) in turn elevates the temperature of the excess unreacted oxygen-containing gas ( 318 ) contained within the combustion zone output (CZ-AP) to a temperature up to 1,500° C. (2,732° F.). It is preferred to operate the combustion zone (CZ-A) at about 1,300° C. (2,372° F.). In embodiments, the combustion stream (CZ-AP) exiting the combustion zone (CZ-A) and entering the reaction zone (CZ-B) operates at about temperature can range from about 1,100° C. (2,0172° F.) to 1,600° C. (2,912° F.). In embodiments, a baffle or impingement plate might be installed to shield the combustion zone (CZ-A) from the reaction zone (CZ-B). 
     Combustion occurs in the combustion zone (CZ-A) to generate CO2, H2O, and heat. Heat generated in the combustion zone (CZ-A) elevates the temperature of the superstoichiometric oxygen-containing gas ( 318 ) which is then transferred to the reaction zone (CZ-B) as an intensely hot combustion stream (CZ-AP). 
     In some embodiments, the burner ( 346 ) is a Helmholtz pulse combustion resonator. An oxygen-containing gas ( 318 ) may be introduced into the outer annular region of the burner ( 346 ) and a hydrocarbon ( 322 ) may be introduced into the central section of the burner ( 346 ). Thus, the burner ( 346 ) may serve to act as an aerodynamic valve, or diode, such that self-aspiration of the oxygen-containing gas ( 318 ) is effected in response to an oscillating pressure in the combustion zone (CZ-A). A burner ( 346 ) may operate as a pulse combustor, and typically operates in the following manner. A hydrocarbon ( 322 ) enters the combustion zone (CZ-A). An oxygen-containing gas ( 318 ) enters the combustion zone (CZ-A). An ignition or spark source (not shown) detonates the explosive mixture during start-up. A sudden increase in volume, triggered by the rapid increase in temperature and evolution of combustion stream (CZ-AP), pressurizes combustion zone (CZ-A). As the hot combustion stream (CZ-AP) expands, the burner ( 346 ) and nozzle ( 347 ) form of a fluidic diode, permit preferential flow in the direction of the reaction zone (CZ-B). The gaseous combustion stream (CZ-AP), exiting combustion zone (CZ-A), possesses significant momentum. A vacuum is created in combustion zone (CZ-A) due to the inertia of the combustion stream (CZ-A) passing through the burner nozzle ( 347 ), and permits only a small fraction of the combustion stream (CZ-AP) to return to combustion zone (CZ-A), with the balance of the combustion stream (CZ-AP) exiting through the nozzle ( 347 ). Because the combustion zone (CZ-A) pressure is then lower than the supply pressure of both the oxygen-containing gas ( 318 ) and the hydrocarbon ( 322 ), the oxygen-containing gas ( 318 ) and the hydrocarbon ( 322 ) mixtures are drawn into combustion zone (CZ-A) where auto-ignition takes place. Again, the burner ( 346 ) and nozzle ( 347 ) constrains reverse flow, and the cycle begins anew. Once the first cycle is initiated, operation is thereafter self-sustaining or self-aspirating. 
     A preferred pulse combustor burner ( 346 ) used herein, and as noted above, is based on a Helmholtz configuration with an aerodynamic valve. The pressure fluctuations, which are combustion-induced in the Helmholtz resonator-shaped combustion burner ( 346 ), coupled with the fluidic diodicity of the aerodynamic valve burner ( 346 ) and nozzle ( 347 ), cause a biased flow of the combustion stream (CZ-AP) from the combustion zone (CZ-A), through the nozzle ( 347 ) and into the reaction zone (CZ-B). This results in the oxygen-containing gas ( 318 ) being self-aspirated by the combustion zone (CZ-A) and for an average pressure boost to develop in the combustion zone (CZ-A) to expel the products of combustion at a high average flow velocity (typically over 300 ft/s) into and through the nozzle ( 347 ). 
     The production of an intense acoustic wave is an inherent characteristic of pulse combustion. Sound intensity adjacent to the wall of combustion zone (CZ-A) is normally in the range of 110-190 dB. The range may be altered depending on the desired acoustic field frequency to accommodate the specific application undertaken by the pulse combustor. 
     Reaction Zone 
     The reaction zone (CZ-B) is configured to react a combined product gas ( 302 ) generated in upstream reactors ( 100 ,  200 ) with the hot excess oxygen-containing gas contained in the combustion stream (CZ-AP) to generate additional hydrogen and carbon monoxide. The reaction zone (CZ-B) of the third reactor ( 300 ) accepts a combined product gas ( 302 ) through a combined product gas input ( 304 ) transferred through the third reactor gas input ( 3 C-IN 1 ). The combined product gas ( 302 ) enters the reaction zone (CZ-B) and is introduced from the second reactor gas output ( 3 B-OUT 1 ) of the Second Stage Product Gas Generation System ( 3 B). The hot combustion stream (CZ-AP) is transferred from the combustion zone (CZ-A) to the reaction zone (CZ-B) through the burner nozzle ( 347 ) at preferably a high velocity to realize a stable flame and enhance mixing and reaction between the combustion stream (CZ-AP) and the combined product gas ( 302 ). 
     Mixing and reaction of the combustion stream (CZ-AP) with the combined product gas ( 302 ) entering the third reactor ( 300 ) must be thorough and nearly instantaneous. Sudden and furious mixing of at least a portion of the first reactor product gas ( 122 ), or the combined product gas ( 302 ), with the combustion stream (CZ-AP) takes place in the reaction zone (CZ-B) of the third reactor ( 300 ). As a result, a reaction zone output (CZ-BP) or a reaction stream, is discharged from the reaction zone (CZ-B) to the cooling zone (CZ-C). 
     The reaction zone (CZ-B) may also accept a second hydrocarbon stream ( 326 ) through a second hydrocarbon stream input ( 328 ) or a second hydrocarbon input ( 3 C-IN 5 ). The second hydrocarbon input ( 3 C-IN 5 ) to the Third Stage Product Gas Generation System ( 3 C) may in some instances be naphtha transferred via a first hydrocarbon output ( 8 -OUT 2 ) from a downstream Upgrading System ( 8000 ). The reaction zone (CZ-B) may also accept a third hydrocarbon stream ( 330 ) through a third hydrocarbon stream input ( 332 ) or a third hydrocarbon input ( 3 C-IN 6 ). The third hydrocarbon input ( 3 C-IN 6 ) to the Third Stage Product Gas Generation System ( 3 C) may in some instances be an off-gas transferred via a second hydrocarbon output ( 8 -OUT 3 ) from a downstream Upgrading System ( 8000 ). The second hydrocarbon stream input ( 328 ) and the third hydrocarbon stream input ( 332 ) may be fluidly in communication with the reaction zone (CZ-B) within the interior ( 301 ) of the third reactor ( 300 ) via a combined hydrocarbon connection (CZC 0 ), combined hydrocarbon transfer line (CZC 1 ) and a combined hydrocarbon input (CZC 2 ). 
     The hot unreacted oxygen-containing gas contained within the combustion stream (CZ-AP) reacts with the combined product gas ( 302 ) from the first reactor ( 100 ) and second reactor ( 200 ). The hot unreacted oxygen-containing gas contained within the combustion stream (CZ-AP) optionally reacts with a second hydrocarbon stream ( 326 ) and/or the third hydrocarbon stream ( 330 ). Intense mixing and exothermic reaction occurs in the reaction zone (CZ-B) between the combustion stream (CZ-AP) and the combined product gas ( 302 ) and hydrocarbons ( 326 ,  330 ). In some instances, near instantaneous blending of the combustion stream (CZ-AP) with the combined product gas ( 302 ) and/or hydrocarbons ( 326 , 330 ) is effectuated. Thus, the reaction zone (CZ-B) also permits the mixing of the combined product gas ( 302 ) and hydrocarbons ( 326 ,  330 ) with the intensely hot combustion stream (CZ-AP) to take place. 
     The reaction zone (CZ-B) permits sufficient residence time for substantially complete reaction of the SVOC, VOC and char contained within at least a portion of the first reactor product gas ( 122 ) to take place with the unreacted hot oxygen-containing gas carried through from the combustion stream (CZ-AP). The reaction zone (CZ-B) permits sufficient residence time for substantially complete reaction of the SVOC, VOC and char contained within the combined product gas ( 302 ) to take place with the unreacted hot oxygen-containing gas carried through from the combustion stream (CZ-AP). The reaction zone (CZ-B) also permits sufficient residence time for substantially complete partial oxidation reaction of the carbon and hydrogen contained within the hydrocarbon stream ( 326 ,  330 ) for conversion into product gas. 
     In embodiments, additional hydrogen and carbon monoxide is generated from the exothermic partial oxidation reaction between the SVOC, VOC, and char contained within the combined product gas ( 302 ) and the hot excess oxygen-containing gas of the combustion stream (CZ-AP). In embodiments, additional hydrogen and carbon monoxide is also generated from exothermic partial oxidation reaction between hydrocarbon streams ( 326 ,  330 ) with the hot excess oxygen-containing gas of the combustion stream (CZ-AP). In embodiments, more hydrogen and carbon monoxide exits the reaction zone (CZ-B) than what enters the reaction zone (CZ-B). The reaction stream (CZ-BP) is transferred from the reaction zone (CZ-B) to the cooling zone (CZ-C). In embodiments, a baffle, or impingement plate, might be installed to shield the reaction zone (CZ-B) from the cooling zone (CZ-C). 
     Cooling Zone 
     The cooling zone (CZ-C) is configured to transfer heat from the reaction stream (CZ-BP) to a heat transfer medium ( 310 ) which can then in turn be used as a reactant ( 106 ,  206 ) in an upstream reactor ( 100 ,  200 ). The cooling zone (CZ-C) is configured to accept a reaction stream (CZ-BP) from the reaction zone (CZ-B) and remove heat therefrom to in turn generate a cooling zone output (CZ-CP) or cooled stream. The cooled stream (CZ-CP) leaving the cooling zone (CZ-C) has a lower, reduced temperature relative to that of the reaction stream (CZ-BP) that enters the cooling zone (CZ-C) from the reaction zone (CZ-C). 
     Removal of heat from the reaction stream (CZ-BP) may be accomplished by use of a third reactor heat exchanger (HX-C) in thermal contact with the interior ( 301 ) of the third reactor ( 300 ). More specifically, the third reactor heat exchanger (HX-C), in thermal contact with the cooling zone (CZ-C) of the interior ( 301 ) of the third reactor ( 300 ), indirectly transfers heat from the reaction stream (CZ-BP) to a third reactor heat transfer medium ( 310 ). The third reactor heat exchanger (HX-C) may be any type of heat transfer device known in the art, and is equipped with a heat transfer medium inlet ( 312 ) and a heat transfer medium outlet ( 316 ).  FIG.  32    depicts a heat transfer medium ( 310 ) being made available and introduced to the heat transfer medium inlet ( 312 ) on the lower portion of the cooling zone (CZ-C).  FIG.  32    also depicts a heat transfer medium ( 310 ) being discharged from the third reactor heat exchanger (HX-C) via an outlet ( 316 ) on the upper portion of the cooling zone (CZ-C). 
     A third reactor heat transfer medium ( 310 ) or a third reactor heat exchanger heat transfer medium input ( 3 C-IN 2 ) is made available to the Third Stage Product Gas Generation System ( 3 C). Specifically, third reactor heat transfer medium ( 310 ) is made available to a steam drum ( 350 ) via a steam drum heat transfer medium supply inlet ( 352 ). A third reactor heat transfer medium valve (VC 5 ), with a controller (CC 5 ) and signal (XC 5 ) is provided to regulate the flow of the heat transfer medium to the steam drum ( 350 ). The heat transfer medium depicted in  FIG.  32    is water and liquid phase water is provided to the third reactor heat exchanger (HX-C) from the steam drum ( 350 ) at a third reactor heat transfer medium inlet temperature (T 0 ). The steam drum ( 350 ) has third reactor steam drum pressure (P-C 1 ). In embodiments, the steam drum ( 350 ) contains liquid and vapor phase water. A portion of the liquid phase water is transferred from the steam drum ( 350 ) via an outlet ( 356 ) and a heat transfer medium conduit ( 362 ) to the third reactor heat transfer medium inlet ( 312 ). 
     The steam drum heat transfer medium outlet ( 356 ) of the steam drum ( 350 ) are in fluid communication with the third reactor heat transfer medium inlet ( 312 ) via a heat transfer medium conduit ( 362 ). The steam drum heat transfer medium reactor inlet ( 354 ) of the steam drum ( 350 ) is in fluid communication with the third reactor heat transfer medium outlet ( 316 ) via a heat transfer medium conduit ( 364 ). The steam drum heat transfer medium outlet ( 358 ) of the steam drum ( 350 ) is in fluid communication with the second reactor heat exchanger (HX-B). More specifically, the steam drum heat transfer medium outlet ( 358 ) of the steam drum ( 350 ) is in fluid communication with the second reactor heat transfer medium inlet ( 212 ) via a heat transfer medium conduit ( 360 ). Thus, the third reactor heat transfer medium outlet ( 316 ) of the third reactor heat exchanger (HX-C) is in fluid communication with the second reactor heat transfer medium inlet ( 212 ) of the second reactor heat exchanger (HX-B) via a steam drum ( 350 ) and heat transfer conduits ( 360 ,  364 ). 
       FIG.  32    depicts a heat transfer medium ( 310 ) being introduced to the inlet ( 312 ) of the third reactor heat exchanger (HX-C) via a steam drum. A portion of the liquid phase heat transfer medium contained within the third reactor heat exchanger (HX-C) accepts heat from the reaction stream (CZ-BP) flowing down through cooling zone (CZ-C) within the interior ( 301 ) of the third reactor ( 300 ). At least a portion of the heat transferred from the reaction stream (CZ-BP) to the heat transfer medium ( 310 ) generates steam which is then transferred back to the steam drum ( 350 ). The vapor phase heat transfer medium ( 310 ) that exits the outlet ( 316 ) of the third reactor heat exchanger (HX-C), and transferred to the steam drum ( 350 ) is then routed to the inlet ( 212 ) of the second reactor heat exchanger via a heat transfer medium conduit ( 360 ) or a second reactor heat transfer medium input ( 3 B-IN 2 ) or a third reactor heat transfer medium output ( 3 C-OUT 2 ). Thus, a portion of the third reactor heat transfer medium ( 310 ) accepts heat from a portion of the heat generated in the third reactor ( 300 ) and is ultimately used as (i) heat transfer medium ( 210 ) in the second reactor heat exchanger, (ii) a reactant ( 106 A,  106 B,  106 C) in the first reactor ( 100 ), and/or (iii) a reactant ( 206 A,  206 B,  206 C) in the second reactor ( 200 ). 
     The Third Stage Product Gas Generation System ( 3 C) outputs a third reactor heat transfer medium output ( 3 C-OUT 2 ) to the Second Stage Product Gas Generation System ( 3 B) as a second reactor heat transfer medium input ( 3 B-IN 2 ). A cooling zone output (CZ-CP) or cooled stream is discharged from the cooling zone (CZ-C) and is introduced to the quench zone (CZ-D). The cooled stream (CZ-CP) leaving the cooling zone (CZ-C) is lesser in temperature than the reaction stream (CZ-BP) entering the cooling zone (CZ-C). 
     Quench Zone 
     The quench zone (CZ-D) is configured to accept a cooling zone output (CZ-CP) or cooled stream, along with a source of third reactor quench water ( 342 ), and output a quench zone output (CZ-DP) or quenched stream. A source of quench water ( 342 ) is introduced to the quench zone (CZ-D) within the interior ( 301 ) of the third reactor ( 300 ). The quench water ( 342 ) is made available to the Third Stage Product Gas Generation System ( 3 C) via a quench water input ( 3 C-IN 7 ). 
     In embodiments, the quenched stream (CZ-DP) may be synonymous with the third reactor product gas ( 334 ) that is discharged from the third reactor ( 300 ) via a third reactor product gas output ( 336 ). The quenched third reactor product gas ( 334 ) is evacuated from the Third Stage Product Gas Generation System ( 3 C) via third reactor output ( 3 C-OUT 1 ) and is made available to a downstream Primary Gas Clean Up System ( 4000 ) via a product gas transferred via the primary gas clean-up input ( 4 -IN 1 ). The quench zone (CZ-D) is also configured to output a third reactor slag ( 338 ) via a third reactor slag output ( 340 ). The slag ( 338 ) may be evacuated from the Third Stage Product Gas Generation System ( 3 C) via a solids output ( 3 C-OUT 3 ). 
     The quench zone (CZ-D) is optional in the event of the need to maximize the heat recovery in a downstream Primary Gas Clean Up Heat Exchanger (HX- 4 ) located in a downstream Primary Gas Clean Up Control Volume (CV- 4000 ). In other embodiments, where the quench stream (CZ-DP) is optional and omitted, the cooled stream (CZ-CP) may be synonymous with the third reactor product gas ( 334 ) that is discharged from the third reactor ( 300 ) via a third reactor product gas output ( 336 ). In embodiments, the product gas, or syngas, that passes through the primary gas clean-up is referred to as a source of conditioned syngas. In embodiments, the product gas, or syngas, that passes through the secondary gas clean-up is referred to as a source of conditioned syngas. 
     Thus, in turn,  FIG.  32    depicts a system and process for the partial oxidation of SVOC and VOC contained within a product gas stream, comprising:
     (a) combusting a hydrocarbon stream with oxygen to form a combustion stream comprised of CO2, H2O, and oxygen;   (b) reacting VOC and SVOC within the combustion stream to form a reaction stream;   (c) cooling the reaction stream with a heat transfer medium;   (d) superheating the heat transfer medium in a second reactor heat exchanger;   (e) introducing the superheated heat transfer medium to a first reactor as a reactant; and,   (f) introducing the superheated heat transfer medium to a second reactor as a reactant.   

     Further,  FIG.  32    depicts a: 
     (a) third reactor ( 300 ) having a third interior ( 301 ) and comprising: a combustion zone (CZ-A) configured to accept both a third reactor oxygen-containing gas ( 318 ) through a third reactor oxygen-containing gas input ( 320 ) and a first hydrocarbon stream ( 322 ) through a first hydrocarbon stream input ( 324 ) and output a combustion zone output (CZ-AP) through a burner ( 346 ); 
     (b) a reaction zone (CZ-C) configured to accept both the product gas created by the first reactor ( 100 ) and product gas created by the second reactor ( 200 ) through a product gas input ( 304 ); and react with the combustion zone output (CZ-AP) to output a reaction zone output (CZ-BP); 
     (c) a cooling zone (CZ-C) configured to accept a third reactor heat transfer medium ( 310 ) through third reactor heat transfer medium inlet ( 312 ); and transfer thermal energy from the reaction zone output (CZ-BP) to the third reactor heat transfer medium ( 310 ) for output via a third reactor heat transfer medium outlet ( 316 ) while also outputting a cooling zone output (CZ-CP); and, 
     (e) a quench zone (CZ-D) configured to accept a third reactor quench water ( 342 ) through a third reactor quench water input ( 344 ) and release third reactor product gas ( 334 ) through a third reactor product gas output ( 336 ). 
     wherein the combustion zone (CZ-A) is configured to combust at least a portion of the first hydrocarbon stream ( 322 ) to generate a combustion zone output (CZ-AP) comprised of a heated stream of oxygen-containing gas, CO2, and H2O; and, 
     wherein the reaction zone (CZ-B) is configured to react the combustion zone output (CZ-AP) with CH4, unreacted carbon within elutriated char, or aromatic hydrocarbons contained within product gas created by both the first reactor ( 100 ) and the second reactor ( 200 ) to generate additional carbon monoxide (CO) and hydrogen (H2). 
     In embodiments, the first reactor ( 300 ) is synonymous with the term steam reformer ( 300 ) since the first reactor steam reforms carbonaceous material in the presence of steam and optionally one or more other gases, e.g., air, carbon dioxide, oxygen, to form a first reactor product gas ( 122 ) including syngas comprising carbon monoxide, hydrogen, char, volatiles and one or more other gases. 
     In embodiments, the second reactor ( 200 ) is synonymous with the expression carbon trim cell ( 200 ), since the second reactor accepts char from the first reactor, and reduces (i.e., “trims”) carbon content by converting it into a second reactor product gas ( 222 ), also including syngas comprising carbon monoxide, hydrogen, volatiles and one or more other gases. 
     In embodiments, the third reactor ( 300 ) is synonymous with the term hydrocarbon reformer ( 300 ) since the third reactor reforms hydrocarbons contained within product gases created by both the first reactor ( 100 ) and the second reactor ( 200 ) into additional carbon monoxide (CO) and hydrogen (H2). This results in an improved syngas having a higher concentration of carbon monoxide and hydrogen, relative to that found in both the first reactor product gas ( 122 ) and the second reactor product gas ( 222 ). 
     While a preferred embodiment includes first, second and third reactors, it is nonetheless possible to have only the first and third reactors, with the char created by the first reactor not being converted into the second reactor product gas ( 222 ), and only the first reactor product gas ( 112 ) being input into the third reactor. 
     The first reactor product gas ( 122 ) has a first H2 to CO ratio and a first CO to CO2 ratio. The second reactor product gas ( 222 ) has a second H2 to CO ratio and a second CO to CO2 ratio. The third reactor product gas ( 334 ) has a third H2 to CO ratio and a third CO to CO2 ratio.

     Product gas, including char and bed material are evacuated from the interior ( 101 ) of the first reactor ( 100 ) en route to the input ( 152 ) of the first solids separation device ( 150 ). Solids including char and bed material are separated out in the first solids separation device ( 150 ) and are transferred via a dipleg ( 244 ) to the input ( 246 ) of a solids flow regulator ( 245 ).

In embodiments, the second reactor pressure (P-B) is about 28 PSIG. In embodiments, the third reactor pressure is about 26 PSIG.

In other embodiments, the first reactor pressure (P-A) may operate at a pressure within the pressure range of about 9 PSIA to about 75 PSIG.  FIG.  33    depicts the first reactor temperature (T-A) between about 320° C. and 569.99° C. (608° F. and 1,057.98° F.) and utilizes an endothermic hydrous devolatilization thermochemical process within the interior ( 101 ). In other embodiments,  FIG.  33    may depict the first reactor temperature (T-A) operating between about 570° C. and 900° C. (1,058° F. and 1,652° F.) and utilizing an endothermic steam reforming thermochemical process within the interior ( 101 ). In other embodiments,  FIG.  33    may depict the first reactor temperature (T-A) operating between about 570° C. and 900° C. (1,058° F. and 1,652° F.) and utilizing an endothermic water-gas shift thermochemical process within the interior ( 101 ). 
     The solids flow regulator ( 245 ) accepts a gas ( 249 ) through a gas input ( 248 ) which prevents backflow and also aides in the transfer of bed material and char from the solids flow regulator ( 245 ) to the interior ( 201 ) of the second reactor ( 200 ). Bed material and char ( 202 ) exit the solids flow regulator ( 245 ) through an output ( 247 ) and are transported to a char input ( 204 ) on the second reactor ( 200 ). 
     The second reactor ( 200 ) has a second interior ( 201 ). The second reactor reactant ( 206 ) is steam transferred from the outlet ( 216 ) of the second reactor heat exchanger (HX-B) to the reactant inlet ( 208 ) of the second reactor ( 200 ). The second reactor ( 200 ) accepts an oxygen-containing gas ( 218 ) through a second reactor oxygen-containing gas input ( 220 ). The second reactor ( 200 ) accepts a second reactor carbon dioxide ( 406 ) through a second reactor carbon dioxide input ( 407 ). 
       FIG.  33    also depicts the second reactor temperature (T-B) to be between 500° C. and 1,400° C. (932° F. and 2,552° F.). The second reactor ( 200 ) of  FIG.  27    has partial oxidation, steam reforming, water gas shift, and dry reforming thermochemical processes taking place therein. 
     The second reactor also has a particulate classification chamber (B 1 ) including a mixture transfer valve (V 9 B), classification gas transfer valve (V 10 B), bed material riser recycle transfer valve (V 11 B), depressurization vent valve (V 12 B), and an inert feedstock contaminant drain valve (V 13 B). The particulate classification chamber (B 1 ), or classifier, has a bed material &amp; inert feedstock contaminant mixture input (B 5 ), classifier gas input (B 6 ), classified recycled bed material output (B 7 ), classifier depressurization gas output (B 8 ), and a classifier inert feedstock contaminant output (B 9 ). The terms classifier, classifier vessel, particulate classification chamber, and variations thereof are treated as synonymous throughout the specification. A table of reference numerals is provided below to avoid confusion. 
     The bed material &amp; inert feedstock contaminant mixture input (B 5 ) on the particulate classification chamber (B 1 ) in fluid communication with the bed material &amp; inert feedstock contaminant mixture output (B 2 ) on the second reactor ( 200 ) via a mixture transfer conduit (B 3 ). The bed material riser recycle transfer valve (V 11 B) is located on the classifier riser (B 17 ) in between the classified recycled bed material output (B 7 ) of the particulate classification chamber (B 1 ) and the classified recycled bed material input (B 27 ) on the second reactor ( 200 ). The depressurization vent valve (V 12 B) is located approximate to the classifier depressurization gas output (B 8 ) to control or regulate classifier depressurization gas (B 18 ) evacuated from the particulate classification chamber (B 1 ). The inert feedstock contaminant drain valve (V 13 B) is located approximate to the classifier inert feedstock contaminant output (B 9 ) to control or regulate classified inert feedstock contaminants (B 19 ) evacuated from the classifier. 
     A bed material and inert feedstock contaminant mixture (B 4 ) is transferred from the interior ( 201 ) of the second reactor ( 200 ) to the interior of the particulate classification chamber (B 1 ) through the mixture transfer conduit (B 3 ). A mixture transfer valve (V 9 B) is interposed in the conduit (B 3 ) in between the bed material &amp; inert feedstock contaminant mixture output (B 2 ) of the second reactor ( 200 ) and the mixture input (B 5 ) on the classifier. The bed material and inert feedstock contaminant mixture (B 4 ) has a bed material portion and an inert feedstock contaminant portion. 
     The classifier gas input (B 6 ) on the particulate classification chamber (B 1 ) is configured to accept a classifier gas (B 16 ), such as carbon dioxide recycled from a downstream Secondary Gas Clean Up System ( 6000 ). The classification gas transfer valve (V 10 B) is located upstream of the classifier gas input (B 6 ) to start and stop the flow of classifier gas (B 16 ) to the particulate classification chamber (B 1 ). The drag of the classifier gas (B 16 ) on the bed material portion supplies an upward force which counteracts the force of gravity and lifts the classified recycled bed material (B 37 ) through the classified recycled bed material output (B 7 ), classifier riser (B 17 ), and into the second reactor ( 200 ) via a classified recycled bed material input (B 27 ). Due to the dependence of gas drag on object size and shape, the bed material portion in the particulate classification chamber (B 1 ) is sorted vertically and can be separated, recycled, and cleaned in this manner. The classified inert feedstock contaminants (B 19 ) left within the particulate classification chamber (B 1 ) may be drained via a classifier inert feedstock contaminant output (B 9 ). 
       FIG.  33    is to be used in conjunction with  FIG.  25    which depicts a listing of valve states that may be used in a variety of methods to operate valves associated with the particulate classification chamber (B 1 ).  FIG.  25    identifies five separate discrete valve states of which any number of states can be selected to result in a sequence of steps for the classification of bed material and recovery of inert feedstock contaminants to prevent defluidization within the second reactor ( 200 ). Although not shown in  FIG.  33   , the following signals are configured to be inputs or outputs from the computer (COMP) for use in the Classification Valve States for Automated Controller Operation of a typical particulate classification procedure of  FIG.  25   : second reactor dense bed zone reactant valve signal (XB 1 ); second reactor dense bed zone oxygen-containing gas valve signal (XB 2 ); second reactor feed zone reactant valve signal (XB 3 ); second reactor feed zone oxygen-containing gas valve signal (XB 4 ); second reactor splash zone reactant valve signal (XB 5 ); and, second reactor splash zone oxygen-containing gas valve signal (XB 6 ). 
     The char ( 202 ) separated out from the first reactor product gas ( 122 ) is reacted in the second reactor ( 200 ) with the reactant ( 206 ), carbon dioxide ( 406 ), and an oxygen-containing gas ( 218 ) to generate a second reactor product gas ( 222 ) evacuated from the second reactor ( 200 ) via a second reactor product gas output ( 224 ). Exothermic reactions take place within the second reactor ( 200 ) between the char ( 202 ) and the oxygen-containing gas ( 218 ) in the presence of the second reactor particulate heat transfer material ( 205 ). 
     A second reactor heat exchanger (HX-B) is immersed beneath the fluid bed level (L-B) of the second reactor ( 200 ) to remove heat from the particulate heat transfer material ( 205 ) and in turn transfer heat to the second reactor heat transfer medium ( 210 ) contained within the second reactor heat exchanger (HX-B). A portion of the heated second reactor heat transfer medium ( 210 ) is used as a reactant ( 106 ,  206 ) in the first reactor ( 100 ) and second reactor ( 200 ). 
     The second reactor product gas ( 222 ) evacuated from the second reactor ( 200 ) through a second reactor product gas output ( 224 ) is routed to an input ( 252 ) of the second solids separation device ( 250 ). The second solids separation device ( 250 ) removes solids from the second reactor product gas ( 222 ) to produce a solids depleted second reactor product gas ( 226 ) that is evacuated from the second solids separation device ( 250 ) through an output ( 256 ) and a solids depleted second reactor product gas conduit ( 228 ). A solids output ( 254 ) on the second solids separation device ( 250 ) is configured to transfer separated solids ( 232 ) from the separation device ( 250 ) via a solids transfer conduit ( 234 ). 
     The char depleted first reactor product gas ( 126 ) is combined with the solids depleted second reactor product gas ( 226 ) to create a combined product gas ( 302 ) that is conveyed to the third reactor ( 300 ) through a combined product gas input ( 304 ). Generally, it is desirable to operate the first reactor and second reactor in a superficial fluidization velocity range between 0.5 ft/s to about 25.0 ft/s.  FIG.  33    depicts the first reactor ( 100 ) operating in a superficial fluidization velocity range between 15 ft/s to about 25 ft/s. In embodiments, as in  FIG.  18   ,  FIG.  19   .  FIG.  24   , and  FIG.  33   , it is preferable to operate the first reactor ( 100 ) in a superficial fluidization velocity range between 0.6 ft/s to about 1.2 ft/s. Specifically, in the embodiments of  FIG.  18   ,  FIG.  19   .  FIG.  24   , and  FIG.  33    it is preferable to operate the first reactor in a superficial fluidization velocity range between 0.8 ft/s to about 1 ft/s. 
     In embodiments, as in  FIG.  26    and  FIG.  33   , it is preferable to operate the second reactor ( 200 ) in a superficial fluidization velocity range between 0.2 ft/s to about 0.8 ft/s. Specifically, in the embodiments of  FIG.  26    and  FIG.  33   , it is preferable to operate the second reactor ( 200 ) in a superficial fluidization velocity range between 0.3 ft/s to about 0.5 ft/s. The second reactor ( 200 ) operates at a superficial fluidization velocity sufficient to drive the fine solids from the interior ( 201 ) towards the second solids separation device ( 250 ) for removal. 
     In embodiments, the carbon conversion rate in the first reactor ( 100 ) is in the range from about 50% to about 100%. In embodiments, the carbon conversion rate in the first reactor ( 100 ) is from about 75% to about 95%. In embodiments, the when the carbon conversion rate in the first reactor ( 100 ) is from about 75% to about 95%, the second reactor ( 200 ) converts the 50% to 99% of the char-carbon transferred from the first reactor ( 200 ) and sent to the second reactor ( 200 ). In some embodiments, the second reactor separated solids ( 232 ) range from about 0% to about 90% carbon and from about 100% to about 10% ash on a weight basis. In some embodiments, the second reactor separated solids ( 232 ) range from about 5% to about 30% carbon and from about 95% to about 70% ash on a weight basis. 
     The embodiment of  FIG.  33    depicts a second reactor ( 200 ) equipped with particulate classification chamber (B 1 ). The particulate classification chamber (B 1 ) may be configured to classify, clean, and recycle bed material back to the interior ( 201 ) of the second reactor ( 200 ) while removing larger objects, such as agglomerates from the system. 
     In embodiments, it is preferable to use Geldart A particles as second reactor particulate heat transfer material ( 205 ) in second reactor ( 200 ). In other embodiments, it is preferable to use a mixture of Geldart B and Geldart A particles as second reactor particulate heat transfer material ( 205 ) in second reactor ( 200 ). Thus, the embodiment in  FIG.  33    shows the second reactor particulate heat transfer material ( 205 ) being transferred to the first reactor ( 100 ) for use as the first reactor particulate heat transfer material ( 105 ). 
     Agglomeration can take place in the second reactor ( 200 ) when the char-ash introduced with the char ( 202 ) to the second reactor ( 200 ) is heated above its softening point temperature, and particles stick together to form larger or agglomerated particles. Agglomeration of char-ash particles together in the second reactor ( 200 ) may be compounded by binding or interlocking of two or more fluidized bed particulates together thus eventually increasing the mean particle size of the bed leading to defluidization. As a result growth and accumulation of agglomerates within the fluidized bed of the second reactor ( 200 ) transitions from proper fluidization to possible economically detrimental defluidization leading to unscheduled process termination and shut down. To mediate agglomeration in the second reactor ( 200 ), the second reactor ( 200 ) can be equipped with at least one particulate classification chamber (B 1 ) to reliably and consistently remove from the system agglomerates from the second interior ( 201 ). 
     Further, since the embodiment shown in  FIG.  33    has a first reactor ( 100 ) that is not equipped with a particulate classification chamber (B 1 ), all of the inert feedstock contaminants introduced to the first reactor ( 100 ) are conveyed to the second reactor ( 200 ) for removal. Thus, the embodiments shown in  FIG.  24    may also be applicable to the second reactor ( 200 ) of  FIG.  33   . 
     The third reactor ( 300 ) has a third interior ( 301 ). The third reactor ( 300 ) is configured to accept a combined product gas ( 302 ), and partially oxidize SVOC, VOC, and char contained therein to generate a third reactor product gas ( 334 ) and heat. The third reactor has a burner ( 346 ) that is configured to accept a first hydrocarbon stream ( 322 ), such as a methane containing gas (e.g.—natural gas) via a first hydrocarbon stream input ( 324 ). The third reactor has a burner ( 346 ) that is also configured to accept a superstoichiometric third reactor oxygen-containing gas ( 318 ) to substantially completely combust the first hydrocarbon stream ( 322 ) to generate a combustion stream including CO2, H2O and heat. Left over, unreacted, oxygen-containing gas is present in the combustion stream. The combustion stream is passed from the burner ( 346 ) of the third reactor ( 300 ) and partially oxidizes the SVOC, VOC, and char contained within the combined product gas ( 302 ) to generate additional hydrocarbon, carbon monoxide and heat. 
     The third reactor ( 300 ) is also configured to accept second hydrocarbon stream ( 326 ) via a second hydrocarbon stream input ( 328 ) and a third hydrocarbon stream ( 330 ) via a third hydrocarbon stream input ( 332 ). The second hydrocarbon stream input ( 328 ) and third hydrocarbon stream input ( 332 ) are in fluid communication with a third reactor via a combined hydrocarbon connection (CZC 0 ), combined hydrocarbon (CZC 1 ), and a combined hydrocarbon input (CZC 2 ). The second hydrocarbon stream ( 326 ), may be naphtha, and the third hydrocarbon stream ( 330 ), may be off-gas, both of which may be transferred to the third reactor ( 300 ) from a downstream Upgrading System ( 8000 ). The carbon and hydrogen contained within the second hydrocarbon stream ( 326 ) and the third hydrocarbon stream ( 330 ) may undergo a thermochemical reaction between the oxygen-containing gas present in the combustion stream transferred from the burner ( 346 ) to the interior ( 301 ) of the third reactor ( 300 ) to generate additional hydrogen, carbon monoxide and heat. 
     A third reactor heat exchanger (HX-C) is in thermal contact with the interior ( 301 ) of the third reactor ( 300 ). The third reactor (HX-C) is comprised of a third reactor heat transfer medium inlet ( 312 ) and a third reactor heat transfer medium outlet ( 316 ) through which a third reactor heat transfer medium ( 310 ) flows. The heat generated by the partial oxidation reaction between the SVOC, VOC, and char contained within the combined product gas ( 302 ) and the oxygen-containing gas present in the combustion stream leaving the burner ( 346 ) is transferred to the third reactor heat transfer medium ( 310 ). 
     A steam drum ( 350 ) is configured to accept the heat transfer medium ( 310 ) from the third reactor heat transfer medium outlet ( 316 ) via an inlet ( 354 ) and transfer conduit.  FIG.  33    portrays the heat transfer medium ( 310 ) transferred to the steam drum ( 350 ) to be liquid phase water. The steam drum is also configured to provide a heat transfer medium ( 310 ) to the third reactor heat transfer medium inlet ( 312 ) via an outlet ( 356 ) and transfer conduit ( 362 ). In embodiments, a supply ( 353 ) of liquid phase water for use as the third reactor heat transfer medium ( 310 ) is made available to the steam drum ( 350 ) via a steam drum heat transfer medium supply inlet ( 352 ) and a third reactor heat transfer medium valve (VC 5 ). The steam drum ( 350 ) is equipped with a pressure sensor ( 370 ) and a level sensor ( 372 ). 
     The pressure sensor ( 370 ) with an integrated steam pressure control valve ( 366 ) maintain the steam drum ( 350 ) at a user-defined pressure and steam is discharged through a steam outlet ( 358 ) and conduit ( 360 ) as necessary to maintain a desired steam drum ( 350 ) operating pressure. A portion of the steam evacuated form the steam drum ( 350 ) is used as the second reactor heat transfer medium ( 210 ) and is routed to the inlet ( 212 ) of the second reactor heat exchanger (HX-B). A portion of the steam evacuated from the steam drum ( 350 ) may be routed elsewhere than the inlet ( 212 ) of the second reactor heat exchanger (HX-B) via a conduit ( 365 ). 
     A portion of the third reactor heat transfer medium ( 310 ) is used as the second reactor heat transfer medium ( 210 ). The second reactor heat transfer medium enters the inlet ( 212 ) of the second reactor heat exchanger (HX-B) at a first temperature T 1 . Heat from the interior ( 201 ) of the second reactor ( 200 ) is transferred through the second reactor heat exchanger (HX-B) and into the second reactor heat transfer medium ( 210 ). The second reactor heat transfer medium ( 210 ) is discharged from the outlet ( 216 ) of the second reactor heat exchanger (HX-B) and enters the first reactor ( 100 ) for use as a reactant ( 106 ). The first reactor reactant ( 106 ) enters the interior ( 101 ) of the first reactor ( 100 ) at a first reactor reactant temperature (TR 1 ), that is greater than the temperature of the heat transfer medium ( 210 ) entering the second reactor heat exchanger, at a first inlet temperature (T 1 ). Thus, a portion of the third reactor heat transfer medium ( 310 ) is used as the reactant ( 206 ) in the second reactor ( 200 ). And a portion of the third reactor heat transfer medium ( 310 ) is used as the reactant ( 106 ) in the first reactor ( 200 ). 
     The third reactor ( 300 ) is configured to output a third reactor slag ( 338 ) via a third reactor slag output ( 340 ). The third reactor is configured to output a third reactor product gas ( 334 ) from a third reactor product gas output ( 336 ) to the inlet ( 373 ) of a Primary Gas Clean Up Heat Exchanger (HX- 4 ). The Primary Gas Clean Up Heat Exchanger (HX- 4 ) has a product gas inlet ( 373 ) for accepting a third reactor product gas ( 334 ) and a product gas outlet ( 375 ) for discharging the product gas at a reduced temperature. The Primary Gas Clean Up Heat Exchanger (HX- 4 ) is configured to remove heat from the third reactor product gas ( 334 ) to a heat transfer medium flowing from the Heat Exchanger (HX- 4 ) from the heat transfer medium inlet ( 376 ) to the heat transfer medium outlet ( 377 ). It is preferable to operate the Primary Gas Clean Up Heat Exchanger (HX- 4 ) with product gas velocities in each of the tubes from about 25 to about 125 ft/s. 
     A product gas outlet conduit ( 378 ) is positioned on the product gas outlet ( 375 ) of the Primary Gas Clean Up Heat Exchanger (HX- 4 ) and is configured to transfer the third reactor product gas to the inlet ( 379 ) of a venturi scrubber ( 380 ). The Venturi Scrubber operates at a temperature below the SVOC condensation temperature and below the dew-point of the excess steam contained within the product gas therefore condensing any SVOC and excess steam out into a liquid phase. 
     Solid char particulates entrained within the product gas come into contact with water provided by a venturi scrubber transfer conduit ( 404 ), and solvent provided by a venturi scrubber transfer conduit ( 393 ), at the divergent section of the venturi scrubber and said solid char particulates act as a nuclei for excess steam condensation and are displaced from the vapor phase and into the liquid phase. Connection X 7  indicates water being transferred from water pump ( 394 ) pump discharge ( 395 ) to the venturi scrubber ( 380 ). 
     A mixture comprising product gas, SVOC, solids, solvent and water, is routed to the lower section of the scrubber ( 384 ) via a venturi scrubber product gas outlet conduit ( 382 ). The venturi scrubber product gas outlet ( 381 ) of the venturi scrubber ( 380 ) and the product gas inlet ( 383 ) of the scrubber ( 384 ) are in fluid communication via a venturi scrubber product gas outlet conduit ( 382 ). 
     The scrubber ( 384 ) serves as an entrainment separator for the venturi scrubber and is configured to receive the product gas, SVOC, solids, solvent and water and separately output a water and solids depleted product gas stream and a second mixture comprising SVOC, solids, solvent and water. The scrubber ( 384 ) also serves to capture one or more of other contaminants present including but not limited to HCl, HCN, NH 3 , H 2 S, and COS. A water and solids depleted product gas stream is evacuated from the scrubber ( 384 ) via a product gas outlet ( 385 ) and outlet conduit ( 386 ). Thus, the product gas emanating from the scrubber ( 384 ) has a depleted amount of solids and water relative to the product gas that is discharged from the third rector ( 300 ). 
     The scrubber ( 384 ), is preferably a vertically oriented cylindrical, or rectangular, pressure vessel having a lower section, and an upper section, along with a central section that contains a quantity of packed media either comprising raschig rings, pall rings, berl saddles, intalox packing, metal structured grid packing, hollow spherical packing, high performance thermoplastic packing, structured packing, synthetic woven fabric, or ceramic packing, or the like, wherein media is supported upon a suitable support grid system commonplace to industrial chemical equipment systems. The upper section of the scrubber ( 384 ) preferably contains a demister to enhance the removal of liquid droplets entrained in a vapor stream and to minimize carry-over losses of the sorption liquid. This demister is also positioned above the scrubber spray nozzle system, comprised of a plurality of spray nozzles, or spray balls, that introduce and substantially equally distribute the scrubbing absorption liquid to the scrubber onto the scrubber&#39;s central packing section so it may gravity-flow down through the scrubber central section. It is preferably to operate the scrubber ( 384 ) from about 50% flooding to 80% flooding. It is also preferable to operate the scrubber ( 384 ) with a pressure drop (in water/ft packing) from about 0.15 to about 0.55. 
     As the product gas passes up through the internal packing of the scrubber ( 384 ), excess steam within the product gas comes into intimate contact with water provided by conduit ( 405 ) and solvent provided by conduit ( 392 ). The water provided by conduit ( 405 ) is cooled prior to being introduced to the upper section of the scrubber ( 384 ) through the scrubber spray nozzle system. Steam is condensed into a liquid phase before being discharged from the scrubber ( 384 ) via the underflow downcomer ( 387 ). A separator ( 388 ), such as a decanter, is positioned to accept the flow of SVOC, solids, solvent and water from the downcomer ( 387 ). In embodiments, a separator ( 388 ) is configured to receive the mixture from downcomer ( 387 ) and separate the water within the mixture based upon immiscibility so that the SVOC, solids and solvent collect together to form a mixture above the water within the separator ( 388 ). The decanter separator ( 388 ) is further configured to separately output the water and the SVOC, solids and solvent mixture. The separator ( 388 ) may be equipped with a level sensor ( 389 ). The scrubber ( 384 ) has a sensor to measure the scrubber pressure (P-S) which in the embodiment of  FIG.  33    operates at a pressure within the pressure range of about 9 PSIA to about 75 PSIG. 
     In embodiments, a process fluid ( 403 ), such as water, sodium hydroxide, or a dispersant, such as Nalco 3D TRASAR® 3DT120, may be added to the scrubber. The Nalco Dispersant (3DT120) is used as a declogger to prevent calcium-rich particles from depositing on the pipe wall and plugging the venturi-gas cooler piping. 
     Through a pump discharge ( 391 ), the solvent pump ( 390 ) is configured to transfer SVOC, solids and solvent to the second reactor ( 200 ) as fuel ( 262 ) via a fuel input ( 264 ). The solvent pump is also configured to transfer the SVOC, solids and solvent to the venturi scrubber ( 380 ) via a venturi scrubber transfer conduit ( 393 ). The solvent pump is also configured to transfer the SVOC, solids and solvent to the scrubber ( 384 ) via a scrubber transfer conduit ( 392 ). 
     Intimate gas to liquid contact within the scrubber ( 384 ) allows for the solvent to both, absorb SVOC from the syngas (if any), and enable solid carbon (if any), and solid ash, to become oleophilic and hydrophobic permitting said solids to become suspended within the solvent or water before both the solvent and carbon are discharged from the scrubber ( 384 ). 
     A heat exchanger ( 399 ) is installed in the water pump discharge ( 395 ) line after the solids separator ( 398 ). The heat exchanger ( 399 ) is preferably of the shell and tube type heat exchanger, wherein syngas steam condensate transferred to scrubbing operations resides on the tube-side, and a cooling water supply ( 401 ), and a cooling water return ( 402 ), communicate with the shell-side of the heat exchanger to fulfill the heat transfer requirements necessary to indirectly remove heat from the tube-side steam condensate recirculation scrubbing liquid. 
     FIG.  34 : 
       FIG.  34    refers to a variation of the system of  FIG.  33    however further including an engine ( 410 ) connected to the scrubber product gas outlet conduit ( 386 ) connected to a shaft ( 416 ), and a generator ( 418 ) and configured for power output ( 420 ). 
       FIG.  34    shows an engine ( 410 ) positioned in scrubber product gas outlet conduit ( 386 ). The engine ( 410 ) has a product gas inlet ( 412 ) and a gas outlet ( 414 ). At least one piston ( 417 ) is contained in at least one cylinder ( 419 ) within the engine ( 410 ). At least one spark plug ( 421 ) is positioned in at least one cylinder ( 419 ) within the engine ( 410 ). The cylinder ( 419 ) is configured to accept product gas through the product gas inlet ( 412 ) of the engine ( 410 ). At least one piston ( 417 ) is configured to reciprocate within the cylinder ( 419 ) so as to subject the product gas to changes of pressure, temperature, volume, addition of heat, and removal of heat in at least one idealized thermodynamic cycle. 
     The high-efficiency, low-emission gas engine ( 410 ) is equipped with a shaft ( 416 ) that is configured to turn a generator ( 418 ) for power output ( 420 ). The utility of the engine ( 410 ) is dependent upon the cleanliness of the product gas evacuated from the scrubber product gas outlet conduit ( 386 ). It is of paramount importance that the product gas transferred from the scrubber ( 384 ) and into the product gas inlet ( 412 ) of the engine ( 410 ) have minimal amount of particulates, SVOC, VOC, and water. 
     The preferred type of engine combusts a product gas having a syngas caloric value ranging from 120 BTU/scf to 400 BTU/scf, with the combustible constituents of the product gas being primarily H2 and CO. The actual or useful horsepower of an engine ( 410 ), usually determined from the force exerted on a friction brake or dynamometer connected to the drive shaft, is preferably within the range of power from a range of about 225 to 750 kWb. Further the operating parameters of the engine are preferably an Otto Cycle, four-stroke, and turbocharged. The preferred compression ratio is from about 9:1 to about 12:1. 
     FIG.  35 : 
       FIG.  35    discloses a pressure-volume diagram describing the idealized thermodynamic cycle of  FIG.  34   . A pressure-volume diagram is shown in  FIG.  35    to describe corresponding changes in volume and pressure in an engine ( 410 ) used to combust product gas for power output ( 420 ). Operation of the engine ( 410 ) can be explained in the following method: 
     Step  410 A to  410 B involves a mass of product gas (H2 and CO) being drawn into the engine ( 410 ) at a constant scrubber pressure (P-S) between about 9 PSIA to about 75 PSIG; 
     Step  410 B to  410 C is an adiabatic (isentropic) compression of the product gas (H2 and CO) as the piston ( 417 ) within the engine ( 410 ) moves from bottom dead center (BDC) to top dead center (TDC) within the cylinder ( 419 ); 
     Step  410 C to  410 D is a constant-volume heat transfer to the working product gas (H2 and CO) from a spark plug ( 421 ) while the piston is at top dead center. This process is intended to represent the ignition of the H2 and CO within the product gas and the subsequent rapid combustion into CO2 and H2O. 
     Step  410 D to  410 E is an adiabatic (isentropic) expansion causing the shaft ( 416 ) of the engine ( 410 ) to turn to drive a generator ( 418 ) for power output ( 420 ); 
     Step  410 E to  410 B completes the cycle by a constant-volume process in which heat is rejected from the generated combustion stream of CO2 and H2O while the piston is at bottom dead center. 
     Step  410 B to  410 A the combustion stream including CO2 and H2O is released via the gas outlet ( 414 ) of the engine ( 410 ).

     As shown in  FIGS.  38  and  39   , the densification system ( 1000 ′) is configured to selectively occupy a retracted state in which: the compression head (AL′) is in the retracted position; the backstop head (ED′) is in the retracted position; and the knock-down head (DD′) is in the retracted position. 
     The prior art systems and methods for the generation of densified carbonaceous materials have many drawbacks. First, U.S. Pat. No. 8,726,800 describes a method and mechanical press system for the generation of densified cylindrical ingots. This patent describes a first pressing ram and a second pressing ram operating in opposite directions and disposed in a compression chamber. However, the method in which it operates makes it not suitable to seal against pressure across the compression chamber. The system described in U.S. Pat. No. 8,726,800 is incapable of sealing against a downstream pressure. It is also unable to develop more than one successive densified ingot at a time within the compression chamber. This is because the developed densified ingot can only be made by both simultaneously compressing the ingot from both sides by the advancing force of both the first pressing ram and a second pressing ram advancing towards each other. This makes it impossible for the compression chamber to simultaneously accommodate a plurality of discrete plugs of compressed material. Further, the disclosure of U.S. Pat. No. 8,726,800 only contemplates densified materials having at most a diameter of 3.9 inches and a length of 5.9 inches, making it impractical to use in large-scale thermochemical applications that require densified plugs of greater diameter and length to meet industrial large feedstock throughputs. 
     In some embodiments, the primary piston cylinder assembly (A 0 ′), first ancillary piston cylinder assembly (B 0 ′), and second ancillary piston cylinder assembly (C 0 ′) can be configured as disclosed in U.S. patent application Ser. No. 14/775,071, filed on Sep. 11, 2015, filed as application No. PCT/US2013/035616 on Apr. 8, 2013 and published as US 2016/0031177. The contents of U.S. patent application Ser. No. 14/775,071, filed on Sep. 11, 2015 are incorporated by reference in its entirety to extent necessary to make, use, and understand to present disclosure. 
     In some embodiments, the densification system ( 1000 ′) disclosure herein can be included as a densification system ( 2 D 0 ,  2 D 0 ′) and a plug control system ( 2 E 1 ,  2 E 1 ′) within a feedstock delivery system ( 2000 ) of a Biorefinery Superstructure System (BSS). 
       FIGS.  38 - 50    elaborate upon a non-limiting embodiment of  FIGS.  7  and  8    and further including a description a combined Densification ( 2 D′) and Plug Control ( 2 E′) subsystem or sequence step of the Feedstock Delivery System ( 2000 ). All of  FIGS.  39 - 50    elaborate upon the densification system ( 1000 ) described in  FIG.  38   . 
       FIGS.  38 - 50    show one example of a combined Densification ( 2 D′) and Plug Control ( 2 E′) subsystem accepting a carbonaceous material ( 2 D- 01 ′), for example, as shown in  FIG.  7   , as an input ( 2 D-IN 1 A) from an output ( 2 C-OUT 1 A) of a Mass Flow Regulation ( 2 C) subsystem. In embodiments, the densification system ( 1000 ′) shown in  FIG.  38    serves the purpose of both the Densification ( 2 D′) and Plug Control ( 2 E′) subsystems or sequence steps of the Feedstock Delivery System ( 2000 ). This is because the design of the densification system ( 1000 ′) accept a carbonaceous material ( 2 D- 01 ′) via an input ( 2 D-IN 1 A) and compresses the carbonaceous material to discharge a densified carbonaceous material ( 2 D- 02 ′), and then a force is exerted by the ram (E 20 ′) to hold plugs of densified carbonaceous material ( 2 D- 02 ′) in position and create a stop against which the last plug is formed. 
     The combined Densification ( 2 D′) and Plug Control ( 2 E′) subsystem is shown as a densification system ( 1000 ′). The densification system ( 1000 ′) is configured to accept a carbonaceous material ( 2 D- 01 ′) and compress the carbonaceous material to discharge a densified carbonaceous material ( 2 D- 02 ′). The densification system ( 1000 ′) includes a densification system ( 2 D 0 ′) comprised of at least a third piston cylinder assembly ( 2 D 3 ′). In embodiments, the third piston cylinder assembly ( 2 D 3 ′) can be a primary piston cylinder assembly (A 0 ′). The Plug Control ( 2 E′) subsystem of the densification system ( 1000 ′) is configured to accept a plug ( 1 P′,  2 P′,  3 P′,  4 P′) of carbonaceous material and exert a force upon the plug ( 1 P′,  2 P′,  3 P′,  4 P′) to hold it in place while subsequent plugs are formed as they are compressed up against the plug ( 1 P′,  2 P′,  3 P′,  4 P′) that has said force exerted upon. 
     The Plug Control ( 2 E′) subsystem is configured to accept a plug ( 1 P′,  2 P′,  3 P′,  4 P′) of carbonaceous material and exert a force upon the plug ( 1 P′,  2 P′,  3 P′,  4 P′) to hold it in place while a first subsequent material is compressed up against the plug ( 1 P′,  2 P′  3 P′,  4 P′) that has said force exerted upon. As a plug is made from the first subsequent material, the Plug Control ( 2 E′) subsystem is configured to exert a force upon the plug formed from the first subsequent material to hold it in place while a second subsequent material is compressed up against the plug formed from the first subsequent material that has a force exerted upon. 
     The Plug Control ( 2 E′) subsystem of  FIGS.  38 - 50    includes a plug control system ( 2 E 1 ′) having a plug control cylinder (E 02 ′). In embodiments, the plug control cylinder (E 02 ′) may be a knock-down piston cylinder assembly (D 0 ′) or a backstop piston cylinder assembly (E 0 ′) or both.

     It will be appreciated that the foregoing examples, given for purposes of illustration, are not to be construed as limiting the scope of this disclosure. Although only a few exemplary embodiments of this disclosure have been described in detail above, those skilled in the art will readily appreciate that many variation of the theme are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this disclosure. Accordingly, all such modifications are intended to be included within the scope of this disclosure that is defined in the following claims and all equivalents thereto. Further, it is recognized that many embodiments may be conceived in the design of a given system that do not achieve all of the advantages of some embodiments, yet the absence of a particular advantage shall not be construed to necessarily mean that such an embodiment is outside the scope of the present disclosure. 
     Thus, specific systems and methods of a feedstock delivery system and a feed zone delivery system have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the disclosure. Moreover, in interpreting the disclosure, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. 
     Although the foregoing text sets forth a detailed description of numerous different embodiments of the disclosure, it should be understood that the scope of the disclosure is defined by the words of the claims set forth at the end of this patent. The detailed description is to be construed as exemplary only and does not describe every possible embodiment of the disclosure because describing every possible embodiment would be impractical, if not impossible. Numerous alternative embodiments could be implemented, using either current technology or technology developed after the filing date of this patent, which would still fall within the scope of the claims defining the disclosure. 
     Thus, many modifications and variations may be made in the techniques and structures described and illustrated herein without departing from the spirit and scope of the present disclosure. Accordingly, it should be understood that the methods and apparatus described herein are illustrative only and are not limiting upon the scope of the disclosure. 
     Unless the context dictates the contrary, all ranges set forth herein should be interpreted as being inclusive of their endpoints, and open-ended ranges should be interpreted to include commercially practical values. Similarly, all lists of values should be considered as inclusive of intermediate values unless the context indicates the contrary. 
     The recitation of ranges of values herein is merely intended to serve as a shorthand method of referring individually to each separate value falling within the range. Unless otherwise indicated herein, each individual value is incorporated into the specification as if it were individually recited herein. All methods described herein can be performed in any suitable order unless otherwise indicated herein or otherwise clearly contradicted by context. The use of any and all examples, or exemplary language (e.g., “such as”) provided with respect to certain embodiments herein is intended merely to better illuminate the disclosure and does not pose a limitation on the scope of the disclosure otherwise claimed. No language in the specification should be construed as indicating any non-claimed element essential to the practice of the disclosure. 
     Groupings of alternative elements or embodiments of the disclosure disclosed herein are not to be construed as limitations. Each group member can be referred to and claimed individually or in any combination with other members of the group or other elements found herein. One or more members of a group can be included in, or deleted from, a group for reasons of convenience and/or patentability. When any such inclusion or deletion occurs, the specification is herein deemed to contain the group as modified thus fulfilling the written description of all Markush groups used in the appended claims. 
     It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc. 
     Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present invention, a limited number of the exemplary methods and materials are described herein. 
     It must be noted that as used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the context clearly dictates otherwise.
