Abstract

PARA-XYLENE IS SEPARATED FROM OTHER C8 ISOMERS AND/OR C9 AROMATICS BY CONTACTING THE PARAXYLENE-CONTAINING FEED MIXTURE WITH AN X OR Y ZEOLITE ADSORBENT HAVING GROUP IA OR IIA CATIONS, E.G BARIUM AND/OR POTASIUM AT EXCHANGABLE CATIONIC SITES. THE PARA-XYLENE IS SELECTIVELY ADSORBED ONTO THE ADSORBENT. THE FEED IS THEN REMOVED FROM THE ADSORBENT AND THE PARA-XYLENE RECOVERED FROM THE RESULTING RICH ADSORBENT BY DESORPTION WITH DIETHYLTOLUENE. THE C9'S AND THE OTHER XYLENE ISOMERS ARE TYPICALLY RECOVERED IN THE DISORBENT-CONTAINING RAFFINATE AND CAN BE SEPARATED FROM THIS DESORBENT BY FRACTIONATION OF THE RAFFINATE AND THE DESORBENT RECYCLED TO THE PROCESS.
