The invention relates to a zeolite adsorbent, which comprises at least one FAU zeolite with layered porosity and contains barium or barium and potassium, and the outer surface area of the zeolite adsorbent is greater than 20 m 2 . g -1 , and the content of the non-zeolite phase is between 6% and 12% by weight relative to the total weight of the adsorbent.n n n The present invention also relates to the use of this zeolite adsorbent as an adsorbent, and also to a method for separating p-xylene from an aromatic isomer portion containing 8 carbon atoms. |
