摘要: Adsorbent compositions for vapor-phase adsorption processes, which are selective para-xylene. Such can be used in gas-phase processes the separation of para-xylene or and ethylbenzene from mixed xylenes a C8 aromatic mixture, respectively. The adsorbent generally comprise materials molecular sieve material binder, wherein composition has macropore volume at least about 0.20 cc/g mesopore less than cc/g.
