Abstract: The invention relates to a process for the liquid-phase separation of xylose from a mixture of C5 and C6 sugars comprising at least xylose and glucose, by adsorption of xylose on a zeolitic adsorbent based on FAU-type zeolite crystals having an Si/Al atomic ratio of less than or equal to 1.5 comprising barium, wherein (a) said mixture is brought into contact with said adsorbent, by liquid chromatography, to obtain a glucose-enriched liquid phase and a xylose-enriched adsorbed phase; and (b) on the one hand, said glucose-enriched liquid phase is recovered and said phase adsorbed on said adsorbent is desorbed by means of a desorption solvent in order to recover the xylose on the other hand.

Abstract: The present invention relates to a zeolitic granular material having a connected zeolitic structure across the entire volume thereof, having high mechanical resistance to crushing in the bed, and optimised material transfer in the macro-mesopores. The invention also relates to the method for preparing said zeolitic granular material, as well as to the use thereof as an adsorbent material in co-current or counter-current liquid phase separation methods, typically in a simulated mobile bed.

Abstract: Provided is a zeolite-based adsorbent in the form of agglomerates, where the adsorbent having a tortuosity factor, calculated from the pore distribution determined by mercury intrusion porosimetry, of greater than 1 and less than 3. The adsorbent also has a porosity as determined by mercury intrusion porosimetry of between 25% and 35%. The adsorbent is useful in the field of separations in particular in a process for separating para-xylene from aromatic hydrocarbon isomer fractions containing 8 carbon atoms.

Abstract: The present invention relates to zeolitic adsorbents based on agglomerated crystals of FAU zeolite containing barium and/or potassium, with large external surface area, combining optimum properties in terms of selectivity and mechanical strength. These adsorbents find applications in the separation of cuts of C8-aromatic isomers and notably of xylenes, in the separation of isomers of substituted toluene such as nitrotoluene, diethyltoluene, toluenediamine, in the separation of cresols, and in the separation of polyhydric alcohols such as sugars.
