Abstract
The present invention relates to zeolite adsorbents based on agglomerated crystals of zeolite(s) comprising barium and strontium These adsorbents have applications in the separation of fractions of aromatic C8 isomers and in particular xylene.
Claims10
Adsorbent based on agglomerated crystals of zeolite(s), said agglomerate comprising:
- at least crystals of FAU zeolite(s), with an Si/Al molar ratio of between 1.00 and 1.50, limits included;
- a weight content of barium ions (Ba2+), expressed by weight of barium oxide (BaO), strictly greater than 30%, relative to the total weight of the adsorbent;
- and
- a weight content of strontium ions (Sr2+), expressed by weight of strontium oxide (SrO), strictly greater than 0.1% and strictly less than 3%, relative to the total weight of the adsorbent.
