Study of methanol to aromatics on ZnHZSM-5 catalyst
ZnHZSM-5上甲醇芳构化反应的研究

ZnHZSM-5 catalysts with different Zn loading were prepared by impregnation,and characterized by means of XRD,BET,NH3-TPD and Py-IR.The effects of Zn content and reaction parameters on the conversion of methanol to aromatics were investigated in a fixed-bed down-flow reactor.The results showed: The yield of aromatics increased by 5% on ZnHZSM-5 with Zn loading of 0.5%,but when the Zn loading was more than 2%,not only did the yield of aromatics decreased,but also the cracking reaction of methanol to carbon mo...
