This refers to zeolitic adsorbents based on small agglomerated crystals of zeolite X comprising barium. These adsorbents find applications in the separation of cuts of aromatic isomers in C₈ and particularly of the xylenes, in the separation of substituted toluene isomers such as nitrotoluene, diethyltoluene, toluenediamine, in the separation of cresols, and in the separation of alcohols polyhydric, such as sugars. |
