| 英文摘要 | nanocrystalline zsm-5 zeolite was modified with tetrapropylammonium hydroxide (tpaoh) solution. the effect of the tpaoh treatment time on the catalytic performance of hzsm-5 was investigated in methanol to gasoline (mtg) reaction. the modified samples were characterized using x-ray diffraction, scanning electron microscopy, al-27 and si-29 magic-angle spinning nuclear magnetic resonance spectroscopy, x-ray photoelectron spectroscopy, n-2 adsorption, and nh3 temperature-programmed desorption. the hzsm-5 structure was basically unchanged after modification, but the relative crystallinity increased and the crystal morphology was more regular. the brunauer-emmett-teller surface area, the micropore surface area, the surface si/al ratio, and the amount of strong acid sites increased; this might be caused by desilication and dealumination, and secondary crystallization of the zeolite during the treatment. the stability of the catalyst was significantly improved after modification, as reflected by the increased lifetime from 70 h to above 170 h in mtg reaction. the catalyst lifetime increased with increasing tpaoh treatment time. hydrogen transfer reactions became faster and led to more isoparaffins and less olefins in the liquid products.
