Title: Study on Pulping of Wheat Straw by Green Liquor Cooking Combine with Oxygen Delignification
Abstract: Pulping performance of wheat straw by green liquor(GL) cooking combine with Oxygen delignification was investigated.The results indicated that the pulp which Kappa number 40~50 were obtained under conditions of total titratable alkali of 16%~20%(as Na2O on straw),sulfidity of 30% and highest temperature of 150~170℃.When the GL pulp was subject to oxygen delignification using alkali 4%~5%,the Kappa number decreased from 47 to around 10.The yields of green liquor cooking and oxygen delignification were 45%~50% and 90% respectively.Around 30% of silica was kept in pulp and the physical properties of GL-O pulp were better than AP-AQ.
