ABSTRACT:
A process for converting a methanol feed to light olefins over a zeolite catalyst comprising at least some crystalline aluminosilicate zeolitic material having a Constraint Index of about 1 to 12 and a silica/alumina mole ratio of at least about 12, e.g., ZSM-5, in the presence of diluent which provides O.sub.2 -containing gas, e.g. air, in the reaction zone under methanol conversion conditions. By using such a ZSM-5 type zeolite catalyst and an oxygen-providing diluent, methanol can be converted to an olefin-containing hydrocarbon product enriched in C.sub.2 to C.sub.4 olefins such as ethylene.
