Abstract

The purpose of the present invention is to prevent the loss of C5 and C6 saccharides and to inhibit the generation of fermentation inhibiting substances in a method for producing ethanol which involves independently hydrolyzing the hemicellulose and the cellulose within a cellulosic biomass and subjecting a saccharification liquid to alcohol fermentation. In this method for producing ethanol first a hemicellulose is saccharified and dissolved into a C5 saccharide by subjecting the slurry of a cellulosic biomass in which the concentration of the cellulosic biomass is between 1 and 5 mass % to hot water treatment at a temperature between 140 and 200°C under a pressure between 1 and 5 MPa. Subsequently a cellulose is saccharified and dissolved into a C6 saccharide by turning a dehydrated cake after the hot water treatment into a slurry having a solid content between 1 and 5 mass% and by subjecting the dehydrated cake to hot water treatment at a temperature between 240 and 300°C under a pressure between 4 and 10 MPa. A saccharification liquid is concentrated to a saccharide concentration of 10 mass% or more by using a concentration device such as a reverse osmosis membrane device and is employed during alcohol fermentation.
