PROCESSING BIOMASS

摘要

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful intermediates and products, such as energy, fuels, foods or materials. For example, systems are described that can use feedstock materials, such as cellulosic and/or lignocellulosic materials, to produce an intermediate or product, e.g., by fermentation.

1. A method of processing biomass, the method comprising:
pretreating biomass with electron beam irradiation; saccharifying the pretreated biomass in an aqueous medium to produce sugars; fermenting the sugars to produce an aqueous solution comprising a fermentation product; and distilling the aqueous solution to concentrate the fermentation product; wherein the aqueous medium comprises water removed during the distilling step.
