The purpose of the project is to evaluate the technical and economic feasibility of producing specific gas products via the catalytic gasification of biomass. The project was comprised of laboratory studies, process development, and economic analyses. The laboratory studies were conducted to develop operating conditions and catalyst systems for generating methane-rich gas, synthesis gases, hydrogen, and carbon monoxide and to gain a fundamental understanding of process chemistry. The process development unit (PDU), previously used for tests at atmospheric pressure, was operated at absolute pressures of up to 10 atm (1000 kPa). A program for use on a microcomputer was written to determine the effect of yield changes at elevated pressures on process economics. Results of these studies confirm the favorable economics for generation of methanol from wood reported previously (Mudge, et al. 1981). As yet, catalyst life in the PDU has not been as long as expected from laboratory studies. Process operations in a large scale fluid bed are technically feasible.
