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.
