Abstract

Process for purifying a gas flow with respect to at least one of the impurities capable of being oxidized and/or reduced which it contains, in which the gas flow is subjected to at least the following steps: PA1 (a) compressing the gas flow to a pressure in excess of atmospheric pressure, PA1 (b) bringing the compressed gas flow into contact with at least a first bed of particles of a material containing at least one metal peroxide, and PA1 (c) bringing the gas flow resulting from step (b) into contact with at least a second bed of at least one catalyst.
