摘要：

The introduction of Ag+ ions into ZSM-5 zeolites appreciably enhances the selectivity for aromatic hydrocarbons in the conversion of methanol. Thus, the yield of aromatics over H-ZSM-5 and Ag-ZSM-5 was 43% and 80%, respectively, at 750 K. The distribution of aromatics over Ag-ZSM-5 at 750 K was 3, 12, 36 and 12% for benzene, toluene, xylenes plus ethylbenzene and C-10+, respectively. It is concluded that Ag+ ions have a capability of efficiently converting alkene intermediates into aromatic hydrocarbons.
