Abstract
Dilule alkali pre-extraction of wheat straw before pulping was carried out, and purification and enzymatic hydrolysis of the extract were conducted, at last, wheat straw pulp was manufactured using the solid material after pre-extraction with low alkali charge. The extract and xylo-oligosaccharides solution, components of the solid material after extraction and the pulp were analyzed, and the properties of the pulp and black liquor, the effect of the pre-extraction were investigated. The results indicated that the yield of xylo-wligosaccharides can reach 7, 22% , and the degree of polymerization of xylo-oligosaccharides is 2. 32 when optimal dosage of alkali 4% ~ 6% in pre-extraction is used. The Kappa Number and viscosity of the subsequent pulp are closely to the control pulp, and brightness, breaking length, tear index and folding endurance are higher than the control. The viscosity of the pulping black liquor is lower than control black liquor, and ihe heal value of black liquor is over 15 MJ/kg and higher than the control.关键词
