1/1 abstract “zeolitic adsorbents, their preparation process and their uses” the present invention relates to zeolitic adsorbents based on small crystals of zeolite x agglomerates comprising barium, combining optimal properties in terms of selectivity and mechanical strength. these adsorbents have applications in the separation of fractions of C8 aromatic isomers and, in particular, xylenes, in the separation of substituted toluene isomers such as nitrotoluene, diethyltoluene, or toluenediamine, in the separation of cresols and in the separation of polyhydric alcohols such as sugars . |
