The present invention relates to a zeolite adsorbent based on small agglomerated zeolite X crystals containing barium and having the best properties of selectivity and mechanical strength.nn n n These adsorbents can be used to separate aromatic C 8 isomer fractions (and, specifically, xylene), to separate substituted toluene isomers (such as nitrotoluene, diethyltoluene, or toluenediamine). , Separation of cresol and separation of polyols (such as sugar). |
