A description is given of agglomerates of faujasite X with an Si/Al ratio of 1, the inert binder of which, on the one hand, has been converted to active zeolite by conversion to zeolite in an alkaline liquor, and which have been subjected, on the other hand, to an exhaustive lithium exchange. These adsorbents develop a nitrogen adsorption capacity (1 bar/25° C.) of at least 26 cm<3>/g, which makes them excellent adsorbents for the non-cryogenic separation of gases from air and for the purification of hydrogen.
