Abstract: This invention relates to a process for the production of hydrogen from a hydrocarbon feedstock and steam comprising: A stage for the production of a synthesis gas in a unit for the steam-reforming of the hydrocarbon feedstock, A stage for shift conversion with steam of the synthesis gas that is obtained in the preceding stage producing a hydrogen stream that contains methane and carbon dioxide, A stage for recovering carbon dioxide and methane, present in the stream that is obtained in the shift conversion stage, in the form of hydrates that produce a stream of pure hydrogen, A stage for regeneration of methane, A stage for recycling methane to steam reforming.
