Abstract

Para-xylene is separated from a feed mixture of C8 isomers of xylene and C9 aromatics by contacting the para-xylene-containing feed mixture with an X or Y zeolite adsorbent having Group IA or IIA cations, e.g., barium and/or potassium, at exchangeable cationic sites. The para-xylene components are selectively adsorbed onto the adsorbent. The non-adsorbed feed is then removed from the adsorbent and the para-xylene recovered from the resulting rich adsorbent by desorption with a desorbent comprising tetralin or alkyl or dialkyl derivatives of tetralin or mixtures thereof. The majority of the C9 aromatics and the C8 xylene isomers are typically recovered in the raffinate andcan be separated from the desorbent by fractionation of the raffinate and the recovered desorbent recycled to the process.
