ABSTRACT:
In an adiabatic pressure swing process for air separation by selective adsorption in at least two zeolitic molecular sieve beds in which air is introduced at below 90.degree.F, the coldest gas temperature in the inlet end is 35.degree.F and the .DELTA.T at least 15.degree.F, the inlet end is heated to maintain the gas at maximum of at least 20.degree.F warmer than without heating, but below 175.degree.F.
