Producing butanol and hydrogen from biomass by fermenting biomass to obtain butanol in a first reaction mixture, removing butanol to obtain effluent, and using the effluent as a substrate in a second reaction mixture

摘要

Combined production of butanol and hydrogen from biomass comprises: (a) fermenting biomass to obtain butanol in a first reaction mixture; (b) removing the butanol from the first reaction mixture to obtain effluent; and (c) using the effluent as a substrate in a second reaction mixture in a process using low substrate concentrations, in particular a hydrogen production process.
