METHOD FOR PRODUCING A HYDROGEN-ENRICHED GAS STREAM FROM HYDROGENATED GAS STREAM COMPRISING HYDROCARBONS

摘要

The invention concerns a method for producing a hydrogen-enriched gas stream from at least one gas stream comprising for the major part hydrogen and a gas stream comprising hydrogen and hydrocarbons, using a pressure-modulated gas adsorption unit, the temperature of the gas stream comprising hydrogen and hydrocarbons being first lowered so as to condense the hydrocarbons.
