Conversion of Methanol to Hydrocarbons on Bimetallic Catalysts on the Basis of ZSM-5

Abstract

The conversion of methanol to hydrocarbons over ZSM-5 zeolite modified with transition metals -Zn, Zr and Lais described. The interdependence of reaction parameterstemperature, contact time, and catalyst acidityin controlling C 2 -C 3 olefins selectivity are is characterized and interpreted. It is found that binary modification of ZSM-5 increased the selectivity of target products. Some of the unique properties of La-Zr/НZSM-5 catalyst are apparently due to the combination of strongly acidic and weak acid sites.
