ABSTRACT:
An adsorptive separation process for separating ethylbenzene from a feed mixture comprising ethylbenzene and at least one xylene isomer, which process comprises contacting the feed mixture with a crystalline aluminosilicate adsorbent comprising type X structured zeolite containing at the exchangeable cationic sites at least one cation selected from the group consisting of cations of elements of Group I-A of the Periodic Table of Elements to effect the selective adsorption of ethylbenzene. The ethylbenzene adsorbed by the adsorbent is thereafter recovered as a purified product. The process can be either in the liquid or vapor phase.
