ABSTRACT:
A process for separating a normal C.sub.6 olefin hydrocarbon from a mixture of the same with a C.sub.6 olefin branched chain and/or cyclic hydrocarbon. The process comprises contacting the mixture at separation conditions with a molecular sieve comprising a crystalline silica. The normal C.sub.6 olefin hydrocarbon is selectively retained and will be recovered from the molecular sieve by displacement with a displacement material comprising pentene-1 or butene-1. The process preferably employs a simulated moving bed.
