Investigation of gasification of biomass in the presence of catalysts
The overall objective of this study is to determine the technical and economic feasibility of catalyzed biomass gasification to produce specific products: (a) methane, (b) hydrogen, (c) carbon monoxide, and (d) synthesis gases for generation of ammonia, methanol, or hydrocarbons. Studies that have been completed and previously reported include: (1) determination of relative gasification catalyst activity, (2) determination of reaction kinetics, (3) evaluation of catalyst-wood contacting methods, (4) development of catalyst combinations on a laboratory scale for direct generation of specific products, and (5) design, construction, and operation of a process development unit (PDU) for evaluation of gasification systems. These studies have illustrated the technical feasibility for generating synthesis gases specifically tailored for production of either methanol, hydrocarbons, or ammonia and for generating a methane rich gas. Work to achieve the objectives of this study has continued. Laboratory studies on combined catalyst systems for methane, hydrogen, and carbon monoxide production were completed. Studies on determination of secondary catalyst life and regeneration were initiated. Seed corn was evaluated as an alternative feedstock for synthesis gas generation. The process development unit (PDU) was not operated while modifications were in progress. The PDU modification will permit operation as a fluid bed system. Feasibility studies involved a search for a computer system to aid in evaluation of different processing schemes. ASPEN (Advanced System for Process Engineering simulation) developed at MIT was selected for use. Details of the results obtained since the last contractors' meeting are presented. Status of the project is also presented.
