The biomass is first processed by thermochemical methods (gasification, pyrolysis), for example, to form synthesis gas, which can be processed further to methanol or Fischer-Tropsch (FT-) hydrocarbons. To gasify solid biomass, both circu-... [Pg.396]

A core aspect of the model is the determination of the chemical conversion of gasifier SG to hydrogen by the RP. For conditions where steam availability is not limiting, the chemical conversion relates to the difference between the initial and final combustion/fuel ratio of the fuel gas. The initial CP/SG ratio is determined by the gasifier and the biomass feedstock. The final CP/SG ratio is determined by the thermochemical properties of the metal oxide material. Ideally the difference between the initial (CP/SG),and final (CP/SG)j , ratios should be as large as possible. In reality the availability of steam for the re-oxidation of the metal oxide is limiting for conditions where the difference in the CP/SG ratios are large. [Pg.196]

In an engineering study, ThermoChem developed several cases for a refuse-derived fuel (RDF) gasifier and apphed them to five options for energy recovery. The gasifier cases were for 227 and 595 megagrams per day (Mg/d) [250 and 655 tons per day (t/d)] RDF facilities 300- and 726-Mg/d (330- and 800-1/d) municipal solid waste equivalents were based on ThermoChem s waste. The major components of the steam reformer consisted of ... [Pg.1059]
