Process for separating ethylbenzene from xylenes by selective adsorption on a Beta zeolite

摘要

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 Beta zeolite. Certain desorbents, of which paradiethylbenzene is preferred, give the zeolite good ethylbenzene selectively over the xylenes.
