Summary:A kind of catalyst reactivation is used in synthesizing ethyl benzene by gas-phase ethylene-benzene catalytic alkylation methods. Said method is composed of simulated moving bed system which is multiple stage reactor of switchable over bed by bed. The reactivated catalyst may achieve the moderate reactivation conditions of normal pressure and constant rate of oxygen, and may also achiere a quick adjustment for switching over, and reactivation period. Thus, it may be raised remarkably the efficiency of catalyst and preventing the temp. traversing.
