IPC: C01B21/09
Filed: 2013-09-24
Abstract: A method of controlling an exothermic or endothermic chemical reaction is provided. The method involves measuring a temperature of a first reactant flowing at a first flow rate, contacting the first reactant with a second reactant flowing at a second flow rate to form a reaction product, measuring the temperature of the reaction product, and determining the temperature difference between the temperature of the first reactant and the temperature of the reaction product. The method can further involve adjusting the flow rate of at least one of the first reactant and the second reactant, or shutting down flow, based on the temperature difference. An apparatus to carry out the method is also provided. The method and apparatus can be useful in controlling many different reactions, including the reaction of sodium hypochlorite and ammonia to form monochloramine.

Abstract: Embodiments of a thermochemical method to convert lignocellulosic biomass to a useful fuel is disclosed in a process sequence resulting in low levels of depositable tars in the output gas stream. One disclosed embodiment comprises performing a sequence of steps at elevated pressure and elevated hydrogen partial pressure, including fast (or flash) hydropyrolysis of a lignocellulosic biomass feed followed sequentially with catalytically enhanced reactions for the formation of methane operating at moderate temperatures of from about 400°C to about 650°C and under moderately elevated pressure (about 5 atm to about 50 atm). A temperature rise in the catalyst above pyrolysis temperature is achieved without the addition of air or oxygen. Gas residence time at elevated temperature downstream of methane formation zones is extended well beyond the time required for methane formation. This sequence results in low depositable tars in the output gas stream. The catalyst promotes both the cracking of pyrolysis gases and reactions with hydrogen to preferentially form methane and non-deposit forming hydrocarbons, and also preferentially promotes coke re-gasification.

Abstract: After the completion of research projects, the surplus research products or prototypes are either stored, consuming a lot of space, or disposed/land filled, incurring cost (significantly in the case of hazardous products or prototypes). Often unrelated researchers at a different geographical location may require the same products or prototypes to advance research in the same field or an entirely different field. In the absence of an efficient method for exchanging the surplus research products or prototypes, replication of the original research to recreate the research product or prototype of choice is the only alternative as these products are not commercially available. The replication of research to produce these products/prototypes is usually time-consuming, expensive, needs a lot of expertise, and generates wastes/hazardous wastes (e.g., in the case of chemicals). Hazardous wastes are an environmental concern. To solve this problem, we have devised a web-based technology platform where researchers having the surplus products/prototypes (owners) can display their products, and the researchers requiring those products (seekers) can search and locate the source of these products/prototypes. The platform can also facilitate financial compensation to the owners by the seekers for the products/prototypes exchanged. This not only saves research funds by preventing the duplication of research, but also saves environment by diverting/minimizing wastes and expedites research and development through the availability of starting materials/intermediates.  Thus, the full potential of a product/prototype can be explored through our efficient exchange platform.  Moreover, some of the research funds can be recovered by generating revenue from the sale of the products/prototypes.
