Properties of Wheat Straw Pulps of Alkaline-Oxygen at Low Temperature
摘要
Abstract
Wheat straw after alkaline-AQ pulping was disposed with oxygen directly without washing. An L9(34) orthogonal test was designed to study the effects of alkali charge, oxygen pressure, cooking temperature and holding time on wheat straw alkaline-oxygen pulping. The result showed alkali charge had the maximum influence on yield, while holding time had the minimum influence. The declined of viscosity was not obvious, alkali charge had the maximum influence on kappa number, while oxygen pressure had the minimum influence. At the optimal conditions, the wheat straw alkaline-oxygen pulp was obtained with yield 52.6%, viscosity 1 042 mL/g, the kappa number 17.9, black liquor viscosity 3.4 mPa.s. Compared with the first stage alkaline pulping, viscosity decreased 5.2%, kappa number reduced 11.8%, black liquor viscosity decreased 33.3%.关键词
