Catalytic conversion of methanol to light olefins

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 an aldehyde-contai...

More Information
Summary: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 an aldehyde-containing diluent comprising formaldehyde, acetaldehyde or mixtures thereof, under methanol conversion conditions. By using such a ZSM-5 type zeolite catalyst and an aldehyde-containing diluent, methanol can be converted to an olefin-containing hydrocarbon product enriched in C2 to C4 olefins such as ethylene.
