The invention relates to zeolite adsorbents based on agglomerated crystals of FAU zeolite containing barium and / or potassium, having a large outer surface, combining optimal properties in terms of selectivity and mechanical strength. These adsorbents are used in the separation of fractions of C8 aromatic isomers and, in particular, xylenes, in the separation of substituted toluene isomers such as nitrotoluene, diethyltoluene, toluene diamine, in the separation of cresols and polyhydric alcohols such as sugars. |
