Abstract
A process for producing synthesis gas from biomass in which biomass is contacted with oxygen and steam, wherein the oxygen is present in an amount effective to oxidize the biomass partially and to heat the biomass to a temperature of at least 500° C. and no greater than 750° C. At least a portion of the partially oxidized biomass then is treated with oxygen and steam to heat the biomass to a temperature of at least 800° C., thereby producing a synthesis gas, which then is recovered.
