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.
