Abstract: Gas mixt. of O2 and N2 esp. air, is fed to a column (I) contg. a synthetic zeolite adsorbent (II) to remove its N2 content. N2  prod. is then desorbed by reducing pressure in (I). Adsorbent (II) has an adjusted hole dia. of 7-10 Angstroms and average contact time of feed gas in column (I) is below 30 secs. as defined by T equals L/V where L is column height of adsorbent, V is superficial velocity of gas mixt.  Recovery rates are high at N2  purities of 99.9% or above.
