摘要：

The influence of ZSM-5 (SiO2/Al2O3 = 50) treatment with a tetrabutylamine hydroxide (TBAOH)/NaOH mixture having different mole ratios on its physicochemical properties and catalytic performance in the reaction of methanol to gasoline (MTG) was investigated. It was found that, with increasing ratio TBA(+)/OH-, the crystallinities, micropore surface areas, micropore volumes, the amounts of strong acid sites and Bronsted acid sites gradually increased, and the mesopore volumes decreased. The treatment with pure TBAOH (TBA(+)/OH- = 1.0) ensured the formation of narrow and uniform intracrystalline mesoporosity and the large amounts of strong or Bronsted acid sites on the zeolite, which contribute to the highest liquid hydrocarbon yield in the reaction of MTG.
