The present invention relates to zeolite adsorbents based on agglomerated FAU zeolite crystals 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 aromatic C isomers, in particular, xylenes, in the separation of isomers of substituted toluens, such as nitrotoluene, diethyl toluene, toluene diamine, in the separation of cresols and polyhydric alcohols, such as sugars. |
