STUDIES ON THE KINETICS AND MECHANISM OF ISOMERIZATION OF CHLOROTOLUENE OVER HZSM-5 ZEOLITE——I.The Initian Kinetics and Experience Rate,Equation of o-chloro-toluene

以平均晶粒度为1.3μ的HZSM-5沸石为催化剂,氯苯为稀释剂,研究了常压、临氢条件下,230～270℃范围内邻氯甲苯异构化初始反应动力学,证实该反应在所取实验条件下在动力学区进行。首次获得了该反应经验速率方程及其参数,并对稀释剂氯苯对反应的抑制作用进行了分析。

The initial kinetics of the isomerization of o-chloro-toluene has beenstudied over a small crystallite HZSM—5 zeolite catalyst in 230～27℃ rangeand at atomsphere pressure when chlorobenzene and H_2 was used as diluentand carrier gas respectively.It has been demonstrated that the reactionproceeded under kinetic controlling.The experience rate equation and itsparameteters are diseribed.The inhibition of the diluent is also discussed inthe paper.
