ABSTRACT:
A process using zeolites, or molecular sieves, for separating an alpha-olefin having five or more carbons and the corresponding internal olefin or olefins. A mixture containing the alpha-olefin and one or more of the corresponding internal olefins is contacted with a zeolite which had previously undergone cation exchange. The selectivity of the zeolite, or molecular sieve, changes and eventually reverses as the carbon number increases. The selectivity is also related to the identity of the cation introduced during the cation exchange.
