Zusammenfassung:	Embodiments of adsorbents for separating para-xylene from a mixture of C8 alkyl aromatic hydrocarbons, methods for making such adsorbents, and methods for separating para-xylene using such adsorbents are provided. In one example, an adsorbent comprises a binderless adsorbent. The binderless adsorbent comprises zeolite X and has a K2O/(K2O + BaO + Na2O) molar ratio of from 0.15 to 0.4. Selon des modes de réalisation, la présente invention concerne des adsorbants destinés à la séparation du paraxylène à partir d'un mélange d'hydrocarbures aromatiques en C8 alkyle, des procédés de fabrication de tels adsorbants, et des procédés de séparation du paraxylène à l'aide desdits adsorbants. Dans un exemple, un adsorbant comprend un adsorbant sans liant. L'adsorbant sans liant comprend une zéolite X et présente un rapport molaire K2O/(K2O + BaO + Na2O) situé dans la plage allant de 0,15 à 0,4.
