The invention concerns a process, an apparatus and a use of the recovery of gaseous hydrogen from a gas containing hydrogen, hydrocarbons, carbon monoxide and possibly sulphur-containing products. The invention is mainly characterized by the fact that before the step of eliminating carbon monoxide in a methanator (8), there is carried out a step of permeation of the gaseous mixture through a membrane and a hydrogen enriched and carbon monoxide depleted permeated product is recovered. <IMAGE> |
