Process for the separation of ethylbenzene |
摘要 |
An adsorptive separation process for separating ethylbenzene from a feed mixture comprising ethylbenzene and a plurality of xylene isomers, which process comprises contacting the feed mixture with an adsorbent comprising strontium exchanged type X or type Y zeolite, selectively adsorbing substantially all of the said xylene isomers to the substantial exclusion of the ethylbenzene and thereafter recovering high-purity ethylbenzene. A desorption step may be used to desorb the adsorbed xylene isomers. The process can be either in the liquid or vapor phase.
