Title: Hydrogenation process for solids-containing  carbonaceous feed materials using thermal  countercurrent flow reaction zone
Inventor: JOHANSON EDWIN S
IPC: C10G1/00
Filed: 1984-11-07
Granted: 1987-09-22
Abstract: ABSTRACT OF DISCLOSURE     Thermal  hydrogenation  of  solids-containing carbonaceous feed  materials  to  produce  hydrocarbon  gaseous and  liquid products  is performed in a thermal  reaction zone,  in which the feed material  flows  generally downwardly countercurrent to upflowing hydrogen and recycled hydrocarbon liquid.   The recycled  hydrocarbon  liquid  is  at  a  rate  sufficient  to control  the  settling of  solids-containing feed through  the reactor, and is obtained from the reaction zone upper end by phase  separation  from  gaseous  effluent  at  reaction  con-ditions.   The gaseous effluent material  is removed from the thermal  reaction zone upper end,  and heavy liquid material containing less  than  about 40 W % solids  is withdrawn from the reaction zone bottom end, with both stream, being passed to further phase separation and distillation steps for reco-very of the hydrocarbon gas and liquid products.  The process is useful  for hydroconversion of solids-containing tar sand bitumen,  shale oil  and particularly for coal, with the coal being  fed  into  the  thermal  reaction  zone  as a coal-oil slurry.     If  desired,  the  heavy  liquid  bottoms  stream withdrawn  from  the  lower end of  the  thermal  reaction  zone containing  unconverted  coal  and  ash  solids  can  be  advan-tageously  passed  to  a  second  reaction  zone  containing  an ebullated catalyst bed for further hydrogenation reaction to increase the conversion and yield of low-boiling hydrocarbon liquid products.

Abstract: ABSTRACT OF THE DISCLOSURE           A laser (21) is frequency modulated by an electrical modulating signal of a bit rate into a modulated signal of a first and a second modulated frequency.  A combination of an optical mixer (27) and an optical detector (31) carries out optical heterodyne or homodyne detection on the modulated optical signal to produce a detected signal having a first and a second frequency component.  A component separator (32) is for selecting only one of the components from the detected signal.  A detector (33) detects the selected component to produce a demodulated electrical signal representative of the modulating signal.  The laser is preferably a semiconductor laser.  More preferably, the semiconductor laser is frequency modulated after the modulating signal is converted to a current of an mBnB code sequence,  when the bit rate is below and above about 10 Mbit/second, either the modulating signal or the m3nB code sequence current is preferably used in frequency modulating the semiconductor laser after caused to pass through a high-pass and a low-pass filter, respectively.

Abstract: ABSTRACT       Method and apparatus for forming a reconsolidated wood product from natural wood which has been rended to form flexible open lattice work webs      of naturally interconnected wood strands.  The webs are laid one over the other in overlapping fashion, treated with a bonding agent, and compressed in a compression apparatus       having two members which are cyclically moved towards each other, to effect compression of the webs, and then moved away from each other to permit further webs to be posi-tioned for compression in the compression device.          Movement of the webs through the apparatus is effected by engaging the bonded webs, after compression and when the members            are moved away from each other, so as to draw following laid in webs      into the space between the members           .

Abstract: SELF-CONTAINED SEWAGE TREATMENT SYSTEM AND METHOD     Abstract self-contained sewage treatment system and method includes a first waterless treating tank operable to separate feculent solids from raw sewage influent in a suspended bio-mass for effective aerobic bacterial digestion in this tank with the cutlet of the waterless tank connected to the inlet of a septic tank where sedimentation of the smaller entrained organic particles in the liquor leaving the waterless  tank can occur and undergo anaerobic bacterial digestion.  The system can include pipe means for distributing the clear liquor from the septic tank in a leach field where it can be disposed of in a safe, pollution-free and environmentally acceptable manner without deleterious effects.          Because the method of treatment effectively removes all of the organic solids from the raw sewage influent by using aerobic digestion followed by anaerobic digestion in sequential steps, the clear liquor  leaving  the  septic  tank  will  be environmentally safe and free of all entrained organic matter.

Abstract: FIELD PRESETTABLE ELECTRONIC ODOMETER     Abstract A microprocessor is utilized to store a total accumulated driven mileage (odometer) signal in a non-volatile random access memory (RAM).  Trip mileage manual pushbuttons are coupled to the microprocessor and enable the calculation and display of elapsed driven mileage (trip mileage), and a unit pushbutton converts the displayed total accumulated driven mileage and/or the elapsed trip mileage from a mile to a kilometer visual display.  The microprocessor effectively retrieves non-volatile stored odometer signals, loads them into a microprocessor volatile memory, increments the volatile memory mileage signal in accordance with signals from an actual mileage sensor and provides a visual mileage display on an odometer display.  The magnitude of the odometer signal stored in the non-volatile memory can be preset to a predetermined mileage after the non-volatile memory is coupled to the microprocessor.  This presetting can only be implemented a maximum of three times and only if a non-volatile, non-presettable actual mileage memory indicates the vehicle has been driven less than ten miles.          In response to a substantial adjustment of the non-volatile stored odometer signal, an overflow flag is non-volatilely stored and the odometer display provides a visual indication that a substantial adjustment of the odometer signal in the non-volatile memory has occurred wherein this visual display is simultaneously provided whenever the odometer display provides a visual indication corresponding to the total accumulated mileage.  The presetting of the odometer signal in the non-volatile RAM is accomplished through utilization of the trip and units manual controls, and the vehicle ignition switch.

Abstract: ABSTRACT OF THE DISCLOSURE           A method is disclosed for producing ammonium salts of sulfomethylated lignins suitable for use as dyestuff and coal-water slurry additives.   The method comprises  the steps of ionizing the phenol component of a lignin material by-product of black liquor from a kraft paper-making process in an alkaline liquid medium, methylolating the lignin material, lowering the pH of the liquid medium  to  an acid pH  to precipitate  the methylolated lignin material, washing the precipitated lignin material with water to remove inorganic salts and residual reactants therefrom, and sulfonating the washed, purified methylolated lignin material with an ammonium salt of a sulphur-oxygen containing compound in a liquid medium.  The washed, purified methylolated lignin material is preferably sulfonated at an acid pH level to minimize the production of electrolytes when the lignin is to be used for dyeing at low pH.   Lignin products produced by the method,  as well as dye and coal-water slurry compositions containing such products are also disclosed.

Arcurate end segments of a pressure member of each unit are positioned in an opposing manner to define a pair of shaft holding spaces.  A spring carried on the rod between the inner unit and a head portion of the rod may be advanced through a threaded connection between an end of the rod and a lock-type nut forming part of the outer unit.  This advancement compresses the spring to force an inner friction surface of the unit pressure member end segments into engagement with an outer surface of a shaft positioned in the respective holding spaces.  This engagement selectively inhibits inadvertent shaft movement to maintain the position of the shaft until shaft movement is desired.
