ABSTRACT:
The invention relates to a process for selectively adsorbing ethylbenzene from a stream containing one or more isomeric xylenes. The ethylbenzene is adsorbed on a gallium Beta zeolite. A desorbent comprising para-dialkylbenzene gives the zeolite good ethylbenzene selectivity over the xylenes.
