Abstract
Process for the purification of a chemically inert gas, containing at least one of the O.sub.2 and/or CO impurities, from at least one of the impurities, characterized in that: a) the gas to be purified is passed through an adsorbent comprising at least one porous metal oxide, the gas having a temperature greater than or equal to -40.degree. C., b) a gas which is substantially purified from at least one of the O.sub.2 and CO impurities is recovered. Device for implementation of the process.

Process for the purification of a chemically inert gas to be purified, containing at least one of O.sub.2 and CO as impurities, from at least one of the impurities, which comprises:
- a) passing the gas to be purified through an adsorbent comprising a mixed oxide of at least two transition metals, said gas having a temperature of between -40.degree. C. and +50.degree. C.;
- b) recovering a gas which is substantially purified from at least one of the O.sub.2 and CO impurities.
