Abstract: The vapor-phase -transport (VPT) method was adopted to prepare the grainy MCM-22 zeolite catalyst. Its physical and textural properties were characterized with XRD,SEM and BET.The catalytic performance of the catalyst was evaluated in a liquid-solid fixed bed reactor for the alkylation of benzene with propylene as a model reaction system.It was found that the MCM-22 zeolite catalyst prepared by the VPT method not only showed good crystallinity and high BET surface area， but also better crystal growth orientation and denser structure.The catalyst showed high activity, selectivity and good stability for alkylation of benzene with propylene, especially better selectivity to the end product cumene.The shaped MCM-22 zeolite catalyst prepared by the VPT method has good prospect of industrial application in synthesis of cumene.
