METHOD FOR PRETREATING BIOMASS TO PRODUCE BIOETHANOL

WIPO Patent Application WO/2010/131829

A1

The present invention relates to a method for producing bioethanol from biomass. The present invention relates to a method for pretreating biomass, which is a material for producing bioethanol, wherein a chemical method and a physical method are mixed. The method of the present invention prevents the generation of several kinds of toxic materials which might cause problems in fermentation, and thus eliminates the necessity of a detoxification process. The method of the present invention uses low concentration acids to eliminate the necessity of a re-enriching process for reutilizing acids, which is required when using high concentration acids. The method of the present invention prevents the saccharification of cellulosic materials to eliminate the necessity of a delignification process which is required in preparing cellulosic ethanol. Thus, the method of the present invention has the advantages of being environmentally-friendly and having low production costs and a high yield rate of bioethanol.
