摘要：

The conversion of methanol to light olefins catalyzed by ZSM-5 zeolites with different SAR or impregnated with phosphorus was investigated. The increase in SAR reduced the density and the strength of the acid sites, favoring both the catalytic stability and the production of light olefins, particularly propene. The incorporation of phosphorous also reduced the density and the strength of the acid sites of HZSM-5 zeolite; besides, BET specific area and microporous volume linearly decreased. The increase of P content decreased the activity and improved the stability. The highest propene/ethene molar ratio was observed for the sample with 4 wt.% of P.
