中文摘要：

甲醇为碱法蒸煮过程中产生的主要醇类大气污染物。本文主要研究了几种常用的非木材原料碱法蒸煮甲醇的发生量与木素和聚戊糖含量的关系，并研究了竹材硫酸盐法蒸煮甲醇产生的历程。实验得出，原料种类不同，其甲醇发生量相差很大。刺竹硫酸盐法蒸煮过程中，甲醇发生量随着木索和聚戊糖溶出量的增大而升高。

英文摘要：

Methanol is the main alcohol of air pollutants generated in the alkaline pulping process. The relationship between the quantity of methanol generated in alkaline processes and lignin and pentosan content of several commonly used non-wood raw materials, as well as the course of methanol formation during sulfate pulping of bamboo, were studied. The results showed that the quantity of generated methanol varied greatly according to the species of raw material. During bamboo kraft pulping process, the amount of methanol increased with the increase of the dissolution of lignin and pentosan.
