Abstract

The invention relates to a technology for preparing bioethanol by converting cellulosic wastes during a simultaneous saccharification and fermentation process, consisting in separating cellulose from hemicellulose by the vapour-phase self-hydrolysis pretreatment method, acid catalyzed at a pH = 2, at a temperature of 180...210°C and at a pressure of 50...70 bar, residence time of 10...15 min, followed by the enzymatic hydrolysis of the solid cellulosic fraction separated by the saccharification method followed by the fermentation process in order to obtain solubilized monosaccharides and, finally, to obtain the bioethanol by the fermentation of glucide fractions and hemicellulose fractions with Saccharomyces cerevisiae at a pH = 4...6 and at a temperature of 30...40°C, for 24...72 h.
