The present invention relates to zeolite adsorbents, their preparation process and their use. The zeolite adsorbent is based on small agglomerated crystals of zeolite X comprising barium, combining the best properties in terms of selectivity and mechanical strength. These adsorbents are useful in the separation of aromatic C isomer fractions and in particular xylenes, in the separation of substituted toluene isomers such as nitrotoluene, diethyltoluene or toluenediamine, in methylbenzene Separation of phenols and use in the separation of polyhydric alcohols such as sugars. |
