SUGAR PRODUCTION PROCESS FROM MATERIALS CONTAINING CELLULOSE AND HEMICELLULOSE, METHOD OF SEPARATION OF ACIDS AND SUGARS FROM PROCESS FLUIDS, METHOD OF FERMENTATION OF SUGARS PREPARED IN THE PROCESS, AND METHOD OF PROCESSING SOLIDS PREPARED IN THE PROCESS

摘要

FIELD: hydrolysis industry. SUBSTANCE: cellulose and hemicellulose in biomass are first subjected to concentrated sulfuric acid-assisted decrystallization and hydrolyzed to form sugar- and acid-saturated hydrolysate. Then, silicon oxides are removed from biomass and processed. Remaining solids are subjected to second decrystallization and repeated hydrolysis. Resulting sugar solution is subjected to microorganism (yeast and bacteria)-assisted fermentation involving simultaneous fermentation of hexoses and pentoses. EFFECT: enhanced process efficiency with no environmental pollution. 60 cl, 3 dwg, 21 ex
