Novel compositions of molecular sieve adsorbents are provided in which at least 50% of the exchangeable cations are selected from those of Li, Ca, Ag and Cu and which have within their pore system metal oxide, metal oxide precursors or mixtures thereof. These compositions are useful for the separation of gases and, in particular, the separation of nitrogen from air to produce oxygen or oxygen-enriched gas.
