ABSTRACT:
A process for converting methanol and/or methyl ether to light olefins over a zeolite catalyst comprising at least some crystalline aluminosilicate zeolitic material having pore windows formed by 8-membered rings of oxygen atoms, e.g., Zeolon 500 or ZSM-34, in the presence of hydrogen, or mixtures of hydrogen and carbon monoxide as a gaseous diluent, at elevated temperature and pressure. By using such zeolite catalysts, hydrogen-containing diluents and reaction conditions, methanol and/or methyl ether can be converted to an olefin-containing hydrocarbon product enriched in ethylene and propylene with enhanced catalyst lifetime.
