The coking and deactivation process of benzene and ethylene alkylation reaction over AB-97 zeolite has been studied systematically. The results of acceleration deactivation reaction indicate that deactivation process go through three phases, high level activity stability period, activity decline period and low level activity stability period. The mechanism of this phenomenon was analyzed by the way of the experiment research of pore structure and acid quality of coked zeolite. It is concluded that reducing the strong acid active centers and crystal outer-surface active centers are benefit to improve the activity stability of zeolite.

在AB-97型分子筛催化剂上对苯/乙烯烷基化制乙苯反应体系的结焦失活历程系统实验研究，催速失活实验结果表明失活历程经历高水平活性稳定期，活性衰退期和低水平活性稳定期三个阶段，并通过对失活催化剂的孔结构及酸性质的实验研究，对这一现象进行了机理分析，认为催化剂改性研究中采用降低强酸活性位和晶粒表面活性位这两种手段都有利于改善催化剂的活性稳定性。
