Abstract

Zéolithe. Elle comprend une zéolithe ayant la structure de la faujasite dont le rapport molaire SiO2 à Al2 O 3 est augmenté, ce qui lui confère une sélectivité d'adsorption meilleure pour le paraxylène en comparaison de celle qu'elle a pour le métaxylène. Séparation des xylènes.Zeolite. It comprises a zeolite having the structure of faujasite, the SiO2 to Al2 O 3 molar ratio of which is increased, which gives it a better adsorption selectivity for paraxylene compared to that which it has for metaxylene. Separation of xylenes.
