ABSTRACT:
Olefins are converted to lower alkene hydrocarbon products, e.g., propene, butenes, and isoalkenes with zeolite MCM-22 catalyst. This catalytic conversion is particularly useful in the selective separation of linear olefins in mixed hydrocarbon streams, employing MCM-22 catalyst to convert these straight-chain unsaturated components to lighter products, particularly, C.sub.3 -C.sub.4 olefins. One potential application of this selective separation is in the removal of linear olefins from FCC gasoline.
