Abstract
A process able to separate ortho-xylene from the other C.sub.8 aromatics. In the process the ortho-xylene-containing feed mixture is contacted with an X-type zeolite having silver cations at exchangeable cationic sites which has been subjected to a reduction step. The ortho-xylene is selectively adsorbed onto the adsorbent. The feed is then removed from the absorbent and the ortho-xylene recovered by desorption with para-diethylbenzene. The process is particularly amenable to the simulated moving bed flow scheme.
