本文采用自制的脉冲微型催化色谱装置,在538～636℃温度范围内,对HZSM—12分子筛的甲苯歧化反应动力学进行了考察,求得表观活化能19.2KCal/mol及吸附热8.3KCol/mol.甲苯歧化在本文实验条件下表现为一级反应动力学特征。
Toluene disproportionation kinetics of HZSM-12 zeolite was investigated in a temperature range of 538 ~ 636 ℃ using a homemade pulsed microcatalytic chromatographic apparatus. The apparent activation energy 19.2KCal / mol and the adsorption heat 8.3KCol / mol. Toluene disproportionation showed the first order kinetic characteristics under the experimental conditions in this paper.
