toluene disproportionation

In toluene disproportionation, the catalytic activity is effected by the acidity and crystal size of catalyst.

对于甲苯歧化反应,其受催化剂的酸性质、晶粒大小等因素综合影响.

The influences of temperature, WHSV and C 10 aromatics content in the feedstock on the catalytic properties of the β zeolite based HAT 097B catalyst in toluene disproportionation and C 9 aromatics transalkylation reactions were investigated.

研究了以β沸石为主体的HAT097B催化剂在催化甲苯和C9芳烃歧化与烷基转移反应中，反应空速、温度及原料中C10芳烃含量对反应性能的影响。

An analysis of the status of the aromatics production is given and a comparison of the economic benefit between traditional disproportionation process and selective is made in the paper. A project of building the traditional toluene disproportionation and transalkylation plant is proposed.

分析了燕化公司芳烃系统生产现状，对比了传统歧化工艺和选择性歧化工艺的经济效益，提出了以传统歧化工艺建设甲苯歧化和烷基转移装置的方案。
