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: PA1 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., PA1 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.
