Abstract

Gases such as He or Ar contg. impurities, e.g. H2, O2, water vapour, or carbon oxides, are purified by contacting at ambient temp. with an adsorption mass consisting of a support carrying Pd and/or Rh. The adsorption mass may contain a molecular sieve e.g. type 13X, in which at least some Na is replaced by Pd and/or Rh. He or Ar may be purified as required when they are released from storage.
