Abstract
Adsorbent compositions for vapor-phase adsorption processes, which are selective for para-xylene. Such compositions can be used in gas-phase adsorption processes for the separation of para-xylene or the separation of para-xylene and ethylbenzene from mixed xylenes or a Caromatic mixture, respectively. The adsorbent compositions generally comprise materials of a molecular sieve material and a binder, wherein the adsorbent composition has a macropore volume of at least about 0.20 cc/g and a mesopore volume of less than about 0.20 cc/g.
