Beschreibung
Zusammenfassung:	The invention relates to aggregate zeolitic adsorbents based on faujasite X type zeolite powder having a low silica content and small crystals, exchanged with barium or based on faujasite X type zeolite having a low silica content and small crystals, exchanged with barium and potassium. The invention also relates to the method for preparing said aggregate zeolitic adsorbents, and also their uses for separating sugars, polyhydric alcohols, isomers of substituted toluene, cresols, or for recovering very high purity paraxylene.
