  • ZSM-5/MCM-48 micro/mesoporous composite materials were successfully prepared by using a two-step synthesis route. XRD, N2 adsorption SEM, TEM, FT-IR, and Py-FTIR were used to characterize the effects of the different crystallization time on the structure, surface acidity and reaction performance of methanol to gasoline. The results indicated that, the catalytic mechanism is the surface modification of mesoporous MCM-48 to microporous ZSM-5. Compared with the conventional ZSM-5 based catalyst, it was found that ZSM-5/MCM-48 composite catalyst had excellent low temperature activity and selectivity of gasoline fraction in MTG reaction, and significantly reduced the yield of total aromatic and durene in the oil.
