不同程度稀酸预处理后杨木枝桠材的物料平衡分析
Analysis of the Mass Balance of Poplar Branch Wood after Dilute Acid Pretreatment with Different Intensities
摘要
Abstract
In order to systematically investigate the effects of acid pretreatment on the lignocellulosic biomass,poplar branch wood was pretreated by dilute acid with different pretreatment intensities.The results showed that much more xylan was dissolved than glucan and Klason lignin during the pretreatment.The dissolution of those compositions increased with the increase of pretreatment intensity.Among different factors of dilute acid pretreatment,the dissolution of acetyl groups was susceptible to acid concentration while the dissolution of xylan and acid soluble lignin was susceptible to tempera-ture.Meanwhile,the lignin granule appeared on the surface of wood chips after the dilute acid pretreatment,and the amount of lignin granule increased with the increase of pretreatment intensity.关键词
