A METHOD FO REACTIVATING AN ADSORBER OF THE CLASS OPERATED AT LOW TEMPERATURE TO ADSORB IMPURITIES FROM A GASEOUS STREAM AND REACTIVATED AT A HIGHER TEMPERATURE TO DESORB THE ADSORBED IMPURITIES COMPRISING THE STEPS OF DESORBING IMPURITIES FROM AN ADSORBER TO BE REACTIVATED BY WARMING THE ADSORBER TO A REACTIVATING TEMPERATURE AT WHICH IMPURITIES ARE DESORBED, THE ADSORBER BEING WARMED BY RECIRCULATING IN A CIRCUIT FOR CIRCULATING FLUID A WARM STREAM OF REACTIVATING GAS FROM WHICH OIL CONTAMINANTS HAVE BEEN REMOVED, THE CIRCUIT INCLUDING THE ADSORBER, REMOVING THE REACTIVATING GAS CONTAINING IMPURITIES FROM THE CIRCUIT, CHARGING THE CIRCUIT WITH A GASEOUS MATERIAL FOR COOLING THE ADSORBER HAVING A SUBSTTANTIALLY LOWER IMPURITY CONTENT THAN THE IMPURITY-CONTAINING REACTIVATING GAS WHICH WAS REMOVED FROM THE CIRCUIT, COOLING THE GASEOUS MATERIAL BY PASSING AT LEAST A PORTION OF THE CHARGE IN THE CIRCUIT IN HEAT EXCHANGE EFFECTING RELATION WITH A COLDER MATERIAL, AND COOLING THE ADSORBER BY RECIRCULATING THROUGH THE CIRCUIT AT LEAST A PORTION OF THE COOLED GASEOUS MATERIAL, BOTH THE REACTIVATING GAS AND GASEOUS MATERIAL FOR COOLING THE ASORBER BEING RECIRCULATED AT PRESSURES NOT LESS THAN ABOUT 500 P.S.I.A.
