Abstract
The present invention relates to zeolite adsorbents based on agglomerated zeolite X crystals comprising barium, potassium and sodium. These adsorbents find applications in the separation of aromatic C8 isomer fractions and especially xylene.
Claims18
A zeolite adsorbent comprising:
- zeolite X crystals;
- and
- barium, potassium and sodium,
- wherein the K2O/(K2O+BaO+Na2O) mole ratio is between 0.08 and 0.086, and
- wherein the content of sodium oxide Na2O is less than 0.3% by weight relative to the total mass of the adsorbent.
