    Abstract: An optimal material composition that allows for the purification of at least one feed component from a fluid feed stream such that the adsorbent has an oxygen capacity of at least 10 weight percent is described. More specifically, the material is an adsorbent for purification of a fluid feed stream having an oxygen to argon selectivity greater than or equal to a ratio of 3:1, said adsorbent being zeolite of type A partially ion exchanged with lithium to create a pore size smaller than type 4A and larger than type 3A zeolites. The non-lithium charge balancing counter cations in the exchanged zeolite are substantially sodium. The adsorbent is in the form of agglomerated particles having at most 20 weight percent of binding agent, said agglomerated adsorbent particles is in the range of 0.4 to 1.2 mm.
