The invention relates to a pressure swing adsorption (PSA) method for separating a gaseous mixture containing hydrogen (H´2?) and hydrocarbon-type (C´n?H´m?) impurities, according to which the gaseous mixture to be purified is reacted with an activated carbon and silica gel so as to adsorb the impurities contained in the gaseous mixture that is to be treated and produce a hydrogen-rich flux as well as a residual gas flux at a regeneration pressure ranging between 2 and 10 bar absolute. The produced residual gas flux can then be fed into the fuel network of a petrochemical plant, particularly a refinery.
La pr~sente invention concerne un proc~d~ PSA de s~paration d~un m~lange gazeux contenant de l~hydrog~ne (H~2) et des impuret~s de type hydrocarbures (C~nH~m), dans lequel le m~lange gazeux ~ purifier est mis en contact avec un charbon actif et du gel de silice de mani~re ~ adsorber les impuret~s contenues dans le m~lange gazeux ~ traiter et ~ produire un flux riche en hydrog~ne, et ~ produire, par ailleurs, un flux de gaz r~siduaire ~ une pression de r~g~n~ration comprise entre 2 et 10 bar abs. Le flux de gaz r~siduaire produit peut ensuite Útre envoyer vers le r~seau combustible d~un site p~trochimique, en particulier une raffinerie.
