The effects of reaction temperature, pressure and WHSV on the performance of ZSM-5/MCM-48 composite molecular sieve catalyst in methanol to gasoline(MTG) process were investigated, and was compared to ZSM-5 catalyst. It was found that the ZSM-5/MCM-48 catalyst was excellent for MTG, the content of aromatics in the liquid products was lowered effectively, and especially the durene content was reduced to 2%(w) or less. Under the appropriate reaction conditions: 380-400 ℃, 0.5 MPa and WHSV 2 h-1, the conversion of methanol, the yield of C+5, the mass fraction of aromatics and the mass fraction of durene in the liquid products were 99.3%, 33.7%, 44.3% and 1.7%, respectively.
