| 中文摘要: |
| 甲醇是碱法蒸煮过程中产生的主要醇类大气污染物。研究了蔗渣烧碱 蒽醌法蒸煮过程中，不同蒸煮条件下甲醇发生量与木素溶出率和聚戊糖溶出率之间的关系。结果表明，在蔗渣烧碱 蒽醌法蒸煮过程中，甲醇发生量随木素溶出率和聚戊糖溶出率的增大而升高；若增加用碱量、提高蒸煮最高温度和延长保温时间，甲醇发生量的变化趋势与木素溶出率的变化趋势相近，而与聚戊糖溶出率的变化趋势有所不同；蒽醌用量为0.025%时，甲醇发生量最低。 |
| Abstract: |
| Methanol is the main alcohol of air pollutants generated in alkaline pulping process. The relationships between the methanol generation and the dissolution of lignin and pentosan in bagasse alkaline cooking under different pulping conditions were investigated. The results showed that the quantity of the methanol generation increased with the increase of the dissolution of lignin and pentosan.The change trend of methanol generation was similar to that of the lignin dissolution, but unlike the dissolution of pentosan. |
