【摘要】 <正> 一、前言 木材和草类是我国制浆造纸的两类主要原料。在世界上制浆造纸科学技术比较先进的国家中,对木材蒸煮脱木素反应历程及蒸煮动力学方面的文献资料报道的较多,而对草类原料制浆机理的研究工作进行得不多。木材和草类原料,无论在纤维的组织结构和化学成份方面,还是在制浆的特点和规律性方面,都有不同程度的差异。因此,很有必要对草类原料的脱木素更多还原

【Abstract】 The rate of delignification of wheat straw sulfate cooking is much faster than that of softwood. The delignification of straw during sulfate cooking belongs to a second-order reaction, and its activation energy is found to be 14895 cal/mol. By using this data, H-factor based on sulfate cooking of wheat straw is calculated.更多还原
