Abstract
Paraxylene is separated from a feedstream containing ethylbenzene and other xylenes by contacting the feedstream preferably with a K-substituted Type Y zeolite, passing through the zeolite a selected additive, and recovering a stream enhanced in concentration of paraxylene relative to ethylbenzene. Preferably, the additive is a cyclic nitrogen containing compound such as pyrrole or pyridine.
