Abstract
Ethylbenzene is separated from a paraxylene depleted feedstream containing meta-xylene by contacting the feedstream with a K-substituted Type Y zeolite, passing through the zeolite a selected desorbent, and recovering a stream enhanced in concentration of ethylbenzene relative to meta-xylene. Preferably, the desorbent is an aromatic hydrocarbon. The zeolite may contain an effective amount up to 10% by weight of total water and up to about 4% by weight methanol.
