Abstract
A process for separating ethylbenzene from a feed mixture comprising ethylbenzene and at least one xylene isomer. The mixture is contacted with an adsorbent comprising a barium cation exchanged type-X zeolite containing from about 3.0 to about 6.0 wt. % H.sub.2 O. The unadsorbed portion of the feed mixture is removed from the adsorbent and the ethylbenzene recovered by desorption with benzene.
