Title:
【発明の名称】ガス流中のオレフィンの2段階選択異性化方法
Document Type and Number:
Japanese Patent JPH0739581
Kind Code:
B2
Abstract:
Olefins in a gasoline boiling range feed stream also containing highly unsaturated hydrocarbons are selectively isomerized by a two step process involving treating the feed stream to reduce the content of highly unsaturated hydrocarbons to form a stable olefinic stream and thereafter contacting the stabilized olefinic stream with an isomerization catalyst containing at least one medium pore molecular sieve at olefin isomerization conditions effective to produce an isomerized product stream having a ratio of branched to unbranched olefins of at least 2:1. The process features yields of C psi + isomerized product and avoids conversion of highly branched paraffins to equilibrium values.
