ABSTRACT:
A process is disclosed for converting a methanol and/or methyl ether-containing reactant feed along with a hydrogen-containing gaseous diluent to a light olefin-containing product over a ZSM-45 aluminosiloicate zeolite based catalyst composition. By using such ZSM-45 zeolite catalysts, methanol and/or methyl ether can be advantageously converted to an olefin-containing hydrocarbon product enriched in C.sub.2 to C.sub.4 olefins. The hydrogen-containing gaseous diluent is co-fed to the conversion reaction zone and the conversion reaction is conducted at a pressure of at least about 3 atmospheres in order to enhance catalyst lifetime.
