摘　　要：Catalytic performance of Mo/HZSM\|5 and Zn modified Mo/HZSM\|5 catalysts under various pretreatment conditions have been studied. The results indicate that the active species exist in oxidative state, and the catalyst pretreated by raising temperature in N\-2 atmosphere exhibits distinguished catalytic activity and benzene selectivity, also higher stability.Catalytic performance of Mo/HZSM\|5 and Zn modified Mo/HZSM\|5 catalysts under various pretreatment conditions have been studied.
