METHOD OF PRODUCING ALCOHOL FROM CELLULOSE-CONTAINING BIOMASS |
摘要 |
A method of producing alcohol from cellulose-containing biomass includes steps (1) to (8): step (1): pretreating a cellulose-containing biomass; step (2): saccharifying the pretreated cellulose-containing biomass obtained in step (1) with a saccharification enzyme; step (3): removing a saccharification residual solid from a saccharification treated product obtained in step (2); step (4): culturing an alcohol fermentation microorganism with an aqueous sugar solution obtained in step (3) as a fermentation raw material; step (5): removing the alcohol fermentation microorganism from a culture liquid containing the alcohol fermentation microorganism obtained in step (4); step (6): distilling the alcohol fermentation liquid obtained in step (5) to recover alcohol; step (7): passing and filtering a distillation residual liquid obtained in step (6) through a reverse osmosis membrane; and step (8): performing treatment of discharging a retentate obtained in step (7). |
