HZSM-5沸石上二甲苯异构化动力学研究

Kinetics Study of the Isomerization of Xylene on HZSM-5 Zeolite

本研究采用不同颗粒度的HZSM-5作为催化剂,研究了二甲苯异构化动力学。反应是在固定床的条件下进行的,通过建立稳态反应模型,求出了异构化反应网络中的每一步动力学参数。从这些参数比较表明,颗粒度的大小对反应活性存在明显的影响。

The isomerization kinetics of Xylene was studied on HZSM-5 Zeolite in different particle size. The reaction took place in the fixed bed reactor. By using steady state model, each step kinetic parameter in the reaction net was acquired. These parameters demonstrate that particle size has great effect on the reaction activity.
