The invention concerns in particular a method for purifying an input mixture comprising carbon dioxide (CO&#x3c;SUB&#x3e;2&#x3c;/SUB&#x3e;) and carbon monoxide (CO), to eliminate the carbon monoxide contained in said mixture, which consists in contacting, at a temperature higher than room temperature, the input mixture with a purifying material comprising at least one metal oxide, so as to bring about the reduction of the purifying material by the input mixture, leading to oxidization of at least part of the CO of the input mixture into CO&#x3c;SUB&#x3e;2&#x3c;/SUB&#x3e;. The invention also concerns a gaseous chilling method and installation integrating such a purifying operation.
