ABSTRACT:
A process for the separation of a para-isomer from a hydrocarbon feed stock containing alkyl-aromatic hydrocarbons having more than eight carbon atoms per molecule which employs a crystalline aluminosilicate adsorbent containing a particular cation or cations to selectively adsorb either a para-, meta-, or ortho- isomer from the feed stock. A feed stock contacts an adsorbent which allows one or more isomers from the feed stock to be selectively adsorbed by the adsorbent. The selectively adsorbed component is thereafter recovered from the adsorbent in a more pure form as compared to the other isomers in the feed stock. The process can be performed in both the liquid or vapor phase.
