[ We claim:] [1.] Process for the separation of hydrogen contained in a gas mixture contaminated by carbon monoxide and containing at least one other impurity selected from the group consisting of carbon dioxide and saturated or unsaturated linear, branched or cyclic C.sub.1 -C.sub.8 hydrocarbons, which comprises bringing the gas mixture to be purified into contact, in an adsorption region, with at least:one first adsorbent selective at least for carbon dioxide and for C.sub.1 -C.sub.8 hydrocarbons, andone second adsorbent which is a faujasite zeolite exchanged to at least 80% with lithium, and having a Si/Al ratio which is less than 1.5, in order to remove carbon monoxide.
