| titleOfInvention | Aggregated zeolitic adsorbent, preparation method thereof and use thereof |
| abstract | FIELD OF THE INVENTION The present invention relates to agglomerated zeolitic adsorbents based on zeolite X having a Si / Al ratio of 1.15 <Si / Al <1.5, consisting of crystals and inert binders having an average diameter of 1.7 μm or less (exchange of the zeolite X At least 90% of the possible cationic sites are occupied by barium ions). These can be obtained by agglomerating zeolite X powder having an average diameter of 1.7 μm or less with a binder, then performing zeoliteization of the binder, exchange of the zeolite ions with barium (and potassium) ions and thus activation of the adsorbent exchanged. have. The adsorbents simultaneously exhibit good selectivity, reduced mass transfer resistance and good mechanical strength, adsorption of paraxylene contained in the C8 aromatic hydrocarbon fraction in the liquid phase, and in particular adsorption, in a simulated moving bed type process. Particularly suitable for the separation of paraxylenes of C8 aromatic hydrocarbon fractions by means of addition to the separation of sugars, polyhydric alcohols, cresols and substituted toluene isomers.n n n Zeolitic adsorbent |
