Claim Text:
1. A process for separating an olefin from a gaseous mixture comprising the olefin admixed with its corresponding paraffin, the process comprising flowing the gaseous mixture through a hollow fiber carbon molecular sieve, wherein the gaseous mixture is comprised of a first and second olefin, the first olefin having one less carbon than the second olefin, and their corresponding first and second paraffin and the hollow fiber carbon molecular sieve has a second olefin/first paraffin selectivity of at least 2.6 whereby the first and second olefin preferentially pass through the hollow fiber carbon molecular sieve forming a permeate gas and the first and second paraffin are preferentially retained forming a retentate gas, and separating the retentate gas and permeate gas.
