PROCESS FOR PREPARING MONOSACCHARIDES AND ARRANGEMENT FOR CARRYING OUT THE PROCESS

摘要

1. A method for recovering monosaccharides from cellulose-containing starting material by hydrolyzation by means of cellulase as well as, if desired, products obtained by fermentation of the monosaccharides, the disintegrated cellulose-containing starting material being reacted with a cellulase-containing aqueous solution at a temperature of between room temperature and about 50 degrees C under atmospheric pressure, characterised in that the reaction is carried out in a plurality of reaction stages and the enzyme- and sugar-containing solution is separated from the solids after each reaction stage, the solids are each supplied to the subsequent reaction stage after washing out the carbohydrates formed, the enzyme- and sugar-containing solutions obtained from the reaction stages are collected and, if desired, are fermented by the addition of sugar-consuming microorganisms.
