用稀土交换的X型分子筛、ZSM-5分子筛和氢型丝光沸石等催化剂可以催化苯气相烷基化反应.为开发苯烷基化新工艺,有必要建立描述失活过程的动力学方程.国外对失活的研究十分活跃,召开了两次专题会议,出版了论文集.本文采用磁驱动内循环无梯度反应器,以苯、乙烯为原料,AF-5分子筛为催化剂,研究了在340～420℃范围内苯烷基化反应的失活动力学.所用AF-5分子筛属ZSM-5系列,比表面为341.1m~2/g,晶粒度为0.04～0.08μ.产物分析所用色谱柱的担体为10％硅酮Ⅰ/釉化6201,柱温130℃,
Catalysts for the gas-phase alkylation of benzene with rare-earth exchanged zeolite X, zeolite ZSM-5 and hydrogen-type mordenite etc. In order to develop a new benzene alkylation process, it is necessary to establish a kinetic equation describing the deactivation process. The study of inactivation is very active, held two special sessions, published a collection of papers.In this paper, magnetic-driven internal circulation gradientless reactor, benzene, ethylene as raw material, AF-5 zeolite as a catalyst, The kinetics of the dealkylation of benzene alkylation reaction at 420 ℃ is shown in Fig. 1. The AF-5 molecular sieve used is ZSM-5 series with a specific surface of 341.1 m 2 / g and a grain size of 0.04-0.08 μ. The carrier is 10% silicone Ⅰ / glaze 6201, the column temperature is 130 ℃,
