ABSTRACT:
A lower alcohol and/or ether feed is selectively converted to a mixture of light olefins, including ethylene and propylene, by catalytic contact of the feed, for example methanol or dimethyl ether, at subatmospheric partial pressure, with certain crystalline aluminosilicate zeolite catalysts exemplified by HZSM-5. Low durene-content gasoline or gasoline blending stock are made from methanol or dimethyl ether by this process.
