Title:
METHOD FOR PRODUCING ALCOHOL FROM CELLULOSE-CONTAINING BIOMASS
Document Type and Number:
WIPO Patent Application WO/2015/005410
Kind Code:
A1
Abstract:
This method for producing alcohol from cellulose-containing biomass includes the following steps (1) to (8). Step (1): a step for pre-processing cellulose-containing biomass. Step (2): a step for saccharification, by means of a diastatic enzyme, of the cellulose-containing biomass after the pre-processing as obtained by step (1). Step (3): a step for eliminating saccharification residual solids from the saccharification processing product obtained from step (2). Step (4): a step for culturing an alcohol fermentation microorganism with the aqueous saccharide solution obtained in step (3) as the starting material for fermentation. Step (5): a step for eliminating the alcohol fermentation microorganism from the culture liquid containing the alcohol fermentation microorganism obtained in step (4). Step (6): a step for recovering alcohol by distillation of the alcohol fermentation liquid obtained in step (5). Step (7): a step for filtering the distillation residue liquid obtained in step (6) through a reverse osmosis membrane. Step (8): a step for wastewater treatment of the retentate obtained in step (7).
