| abstract |
The present invention relates to a zeolite sorbent comprising at least one LSX zeolite having a spore-forming structure (FAU) and containing barium and / or potassium wherein the outer surface area of the zeolite sorbent, as measured by nitrogen absorption, 20 m 2 .g -1 ~ 100 m 2 .g - 1, and includes the end value of (terminals). The present invention also relates to a method for separating para-xylene from aromatic isomeric fractions having 8 carbon atoms, as well as the use of such a zeolite absorbent as adsorbent material. |
