A process and apparatus for preparing a flow which is substantially purified with respect to at least one of the impurities O.sub.2 and CO, according to which: a) a flow to be purified, comprising at least 90 mol % of a compound chosen from nitrogen, helium, neon, argon, krypton, xenon or a mixture of these compounds and at least one of the impurities O.sub.2 and CO, is cooled to a temperature of less than -40.degree. C.; b) the cooled flow is passed through an adsorbent for the adsorption of at least one of the impurities O.sub.2 and CO, the adsorbent comprising at least one porous metal oxide; c) a flow which is substantially purified with respect to at least one of the impurities O.sub.2 and CO is recovered.
Process for preparing a flow which is substantially purified with respect to at least one of the impurities O.sub.2 and CO, the flow to be purified being other than liquid nitrogen, and comprising at least 90 mol % of a compound selected from the group consisting of nitrogen, helium, neon, argon, krypton, xenon or a mixture thereof, the process comprising:
