Abstract: The invention relates to a process for selectively absorbing ethylbenzene from a stream containing one or more isomeric xylenes. The ethylbenzene is adsorbed on an Rb-substituted Type X zeolite. Certain desorbents, of which n-alkylbenzenes are preferred, give the zeolite good ethylbenzene selectivity over the xylenes.

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.
