Purdy, K R; Gorton, C W; Knight, Jr, J A

Biomass feedstock raw material is converted to synthesis gas by drying and sizing biomass raw material, pyrolyzing the processed biomass in intimate mixture with inert gases such as combustion products, thereby obtaining a product mixture of char, pyrolysis oil, and pyrolysis gas, and gasifying the char and some of the pyrolysis oil in the presence of steam and oxygen at a temperature sufficient to form the synthesis gas product substantially comprising carbon monoxide and hydrogen.
