Complex processing of plant raw materials for furfural and glucose production

Abstract

Data on the dynamics of furfural yield from wheat straw, corn cobs, birch sawdust, oat husk and sugar beet pulp in a narrow temperature range (180 – 190 ° C) were obtained. Low-concentrated solutions of sulfuric and phosphoric acids were used. Enzymatic hydrolysis of cellulosic residues was conducted. It was shown that the maximum yield of glucose in birch sawdust was 21.8%, in the corn cobs 18.6%, in wheat straw 19.4%, in sugar beet pulp 15.8 % of absolutely dry substance respectively.
