A system for purifying gas in which one or more main adsorbers containing a gas-adsorbent comprising a molecular sieve carbon (MSC) or the like is connectable in series to a supplementary adsorber containing a substantially smaller amount of the gas-adsorbent in the range of from 5 to 50% of the adsorbent contained in the main gas-adsorbers. The main gas-absorbers are connectable in parallel so that when the gas-adsorbent in one of the main absorbers is being regenerated, and vice versa, the other main gas-adsorber can function independently to adsorb gas or can be connected in series with said supplementary gas-adsorber so that the purification of gas can be continuously effected while one or the other of the main gas adsorbers is being regenerated. The supplementary gas absorber, when connected in series with either of the main adsorbers, functions to effectively finish or substantially complete utilization of the gas-adsorbent in the main adsorbers so that the adsorbers are utilized to maximum efficiency during a minimal time interval.
