Gajda, G J

This patent describes a process for the isomerization of isomerizable olefins in a feed stream consisting essentially of an olefin-containing gasoline-range stream produced by a catalytic cracking process and containing highly unsaturated hydrocarbons. It comprises selectively reducing the content of highly unsaturated hydrocarbons in the feed stream to produce a stable olefinic stream, and contacting the stable olefinic stream at olefin-isomerization conditions with an isomerization catalyst containing at least one medium-pore molecular sieve to produce an isomerized product having a ratio of branched to unbranched olefins of at least about 2.
