Abstract
Ethanol and other liquid products are produced from biomass using indirect gasification of the biomass to produce a syngas containing CO2, CO, H2 and methane that passes the syngas without substantial removal of the methane to a fermentation zone for the conversion of the CO and CO2 and H2 to ethanol and the production of a methane rich stream followed by the methane reforming of the methane rich stream to produce additional CO and CO2 and H2 that passes to the fermentation zone.
