SELECTIVE ADSORPTION OF ETHYLBENZENE FROM XYLENES ON TYPE X ZEOLITE

SELECTIVE ADSORPTION OF ETHYLBENZENE FROM XYLENES ON TYPE X ZEOLITE

The invention relates to a process for selectively adsorbing 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 selectiv...

Zusammenfassung:The invention relates to a process for selectively adsorbing 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.
