SYSTEM AND METHOD FOR TREATING BIOMASS

Title:

SYSTEM AND METHOD FOR TREATING BIOMASS

Document Type and Number:

WIPO Patent Application WO/2011/037194

Kind Code:

A1

Abstract:

A system (A) for treating a biomass, comprising: a pressurized hot water reaction unit (1) whereby, using pressurized hot water, the biomass is hydrolyzed under first reaction conditions for degrading hemicellulose to give a first polysaccharide solution containing xylooligosaccharides, and then said biomass is hydrolyzed under second reaction conditions for degrading cellulose to give a second polysaccharide solution containing cellooligosaccharides; a first catalytic reaction unit (2) whereby the first polysaccharide solution flowing out from the pressurized hot water reaction unit (1) is hydrolyzed using a solid acid catalyst to give a first monosaccharide solution containing xylose; and a second catalytic reaction unit (3) whereby the second polysaccharide solution flowing out from the pressurized hot water reaction unit (1) is hydrolyzed using a solid acid catalyst to give a second monosaccharide solution containing glucose:
