method for separation of buten - 1 of a buten - 1 and c amp; amp; darr; 4 amp; amp; darr; hydrocarbon containing raw material

摘要

A process for the separation of butene-1 from other C4 mono-olefins. A feed stream containing butene-1 is contacted with a K-X zeolite which selectively adsorbs butene-1. The butene-1 is desorbed using a mixture of hexene-1 and cyclohexene or cyclohexane.
