Abstract

The invention provides a method for improving the bagasse enzymolysis efficiency through delignification pretreatment and addition of an additive. The method comprises the steps of delignification pretreatment of a bagasse raw material, enzymolysis and the like. The air-dried and smashed bagasse raw material is mixed with a sodium hydroxide solution with a certain concentration or an acid sodium chlorite solution with a certain concentration, a reaction is conducted at the temperature of 20-180 DEG C for 0.5-12 hours for pretreatment, and pretreated residues rich in cellulose are obtained; cellulase and the additive are added into the residues for enzymolysis, so that the enzymolysis efficiency is improved. According to the method, through sodium hydroxide or sodium hypochlorite pretreatment and addition of the additive in the enzymolysis stage, the enzymolysis efficiency is improved, the enzymolysis time is shortened, the glucose production cost is reduced, and the method has a good application prospect.

Description

Technical field

[0001] The invention relates to a method for efficient conversion and utilization of biomass, in particular to a method for bagasse raw materials to be pretreated by delignification and additives to improve the efficiency of bagasse enzymatic hydrolysis. Background technique

[0002] As energy shortages and environmental issues continue to emerge, biomass as a renewable resource that can be converted into liquid fuels is receiving increasing attention. Among the abundant biomass resources on the earth, the liquid fuel made from lignocellulosic biomass has attracted the most attention.

[0003] The method of making liquid fuel from lignocellulosic biomass is to hydrolyze the hemicellulose and cellulose in the raw material into monosaccharides such as xylose and glucose, produce ethanol through fermentation, or synthesize liquid fuel such as fuel oil through catalysis. However, because the cellulose in the biomass raw material is closely connected with hemicellulose ...
