| titleOfInvention | Separation of C8 aromatic isomers |
| abstract | A process for the adsorption separation of C8 aromatic isomers which comprises the steps of: (a) Supplying a C8 aromatic isomer mixture to a separation zone packed with a zeolite adsorbent to form an C8 aromatic isomer mixture adsorption band, the zeolite being a faujasite structured zeolite where at least about 60% of the exchangeable cation sites are replaced by potassium ion, and the remaining exchangeable cation sites being replaced by at least one metal cation selected from the group consisting of sodium, lithium, rubidium, cesium, magnesium, calcium, strontium, barium, nickel, copper, silver, manganese, cadmium, thallium and lanthanum ions; (b) Supplying a desorbent to the separation zone to develop the C8 aromatic isomer mixture adsorption band, the desorbent being an ether compound having a selectivity of about 0.3 to about 3.0 over para-xylene measured at a concentration of about 10 to about 90% by weight of the ether compound in the mixture of the ether compound and para-xylene; (c) Repeating the step (a) and the step (b) alternately to effect the migration of the C8 isomer mixture adsorption band; and (d) Collecting the entire amount of the C8 aromatic isomer in fractions at the outlet of the separation zone. |
