The invention relates to a PSA, especially VSA, process for separating a stream of gas, such as air, containing at least one first compound, such as nitrogen, which is preferentially adsorbed on at least one adsorbent and at least one second compound, such as oxygen, which is adsorbed less preferentially on at least the said adsorbent than the said first compound, in which process the said adsorbent comprises at least particles of a zeolite having an Si/Al ratio of less than or equal to 5 and chosen from zeolites of X or A type, the said zeolite having a kinetics coefficient (a k) and an intrinsic strength (.alpha.), with: a k > 0.5 s-1 and 0.10 < .alpha. < 2. The invention also relates to an adsorbent for the non-cryogenic separation of gases, especially the gases from air and from syngas.
