ABSTRACT:
Dual desorbent composition and/or dual temperature technique, when employed in a simulated moving-bed adsorption-desorption separation system embedded with a solid sorbent comprising certain sieves, e.g., Rb-exchanged Type X crystalline aluminosilicate sieve, which preferentially adsorb ethylbenzene, entails an improved separation and recovery of ethylbenzene from C.sub.8 aromatic feedstreams as sorbate product. Further, certain specific sieves, which preferentially adsorb xylene isomers, i.e., orthoxylene, metaxylene and paraxylene, may also be employed, in said simulated process utilizing the dual desorbent composition and/or the dual temperature concept, in order to effect the improved separation and recovery of ethylbenzene from its C.sub.8 aromatic isomers as raffinate product.
