| abstract |
The present invention includes at least one FAU zeolite adsorbent with hierarchical porosity, containing barium or barium and potassium, having an outer surface greater than 20 m2.g-1, and the proportion of non-zeolite phase being 6 to 6% by weight relative to the total adsorbent weight. It relates to a zeolite adsorbent located between 12. The present invention also relates to the process of separating para-xylene from aromatic isomer fractions of 8 carbon atoms, as well as the use of such a zeolite adsorbent as an adsorption agent. |
