Claim 0:
1. A pressure swing adsorption process for separating a pressurized feed supply gas containing at least one more rapidly adsorbable component and at least one less rapidly adsorbable product gas component which comprises continuous feeding of a supply gas into a feed input end of an adsorber bed containing at least one solid adsorbent which kinetically adsorbs the more rapidly adsorbable component and withdrawing the least rapidly adsorbable component from an exit end of the adsorber bed, which has at least 2 beds in service in which the continuous feeding of the supply gas sequentially through each of the adsorber beds produces product gas by using continuous feed gas, a constant product gas step, a product pressurization step, a high pressure equalization step, a product make step that overlaps with feeding the bed, at least one equalization up step and at least one low pressure equalization down step, a blow down step to depressurize the bed, wherein there is no purge provided to any bed during any step in the PSA process.
