Progress on catalyzed steam gasification of biomass

TL;DRAbstract

The overall objective of the PNL studies is to evaluate the technical and economic feasibility of producing specific gas products via catalytic gasification of biomass. Specific products that are being studied include (a) methane, (b) synthesis gases for production of ammonia, methanol, and hydrocarbons, (c) hydrogen, and (d) carbon monoxide. In the studies, yields of high-value, gaseous products from a single-reaction stage are enhanced by the proper choice of reactants, operating conditions, and catalyst combinations. Gaseous products, successfully produced by the various steam gasification systems employed to date, include synthesis gases for hydrocarbon, methanol, and ammonia generation and a methane-rich gas. This report details progress of the laboratory studies, process development unit (PDU) studies, and economic analyses conducted at PNL since the eleventh Contractors' Meeting in September 1980. Laboratory studies are presently concentrated on development of regenerable cataly
