Process for producing hydrogen from a gas mixture comprising hydrogen, CO2, CO, CH4 and water, employing a CO2 PSA unit, a cryogenic unit and an H2 PSA unit, in which process: a) said gas mixture is introduced into the CO2 PSA unit, producing a CO2-enriched fraction and CO2-depleted fraction; b) CO2-enriched fraction is introduced into the cryogenic unit, producing a CO2-enriched fraction and an H2-enriched fraction; c) the H2-enriched fraction is recycled upstream of the H2 PSA unit; and d) the CO2-depleted fraction coming from step b) is introduced into the H2 PSA unit, producing a hydrogen-enriched stream and a waste gas.

Procédé de production d'hydrogène à partir d'un mélange gazeux comprenant de l'hydrogène, du CO2, du CO, du CH4 et de l'eau, mettant en oeuvre un PSA CO2, une unité cryogénique et un PSA H2, dans lequel : a) on introduit ledit mélange gazeux dans le PSA CO2, produisant une fraction enrichie en CO2 et une fraction appauvrie en CO2; b) on introduit la fraction enrichie en CO2 dans l'unité cryogénique, produisant une fraction enrichie en CO2 et une fraction enrichie en H2; c) on recycle la fraction enrichie en H2 en amont de l'unité PSA H2; et d) on introduit la fraction appauvrie en CO2, issue de l'étape b), dans l'unité PSA H2, produisant un flux enrichie en hydrogène et un gaz résiduaire.
