Method of determining, as a property of an adsorbent, the selectivity for one component of a liquid charge composition with respect to a reference component of said charge composition

摘要

An adsorbent may be tested at ambient temperature to determine its selectivity for one component of a charge liquid composition with respect to a reference component of the charge composition by equilbration at ambient temperature in the presence of an essentially inert liquid charge; the results determined at e.g. room temperature of e. g. 70° F. are found to permit separation of xylenes at elevated temperatures of typically 340° F.
