Abstract

The present invention relates to a zeolite absorbent comprising at least one FAU zeolite with hierarchical porosity and comprising barium or barium and potassium, and the external surface area of which is greater than 20 m·g, and the non-zeolite phase content being between 6% and 12% by weight with respect to the total weight of the absorbent. The present invention also relates to the use of such a zeolite absorbent as an adsorption agent, as well as the method for separation of para-xylene from aromatic isomer fractions with 8 carbon atoms.
