HYDROGEN REFORMING METHOD AND HYDROGEN REFORMING DEVICE USING OXYGEN-PERMEABLE MEMBRANE

摘要

Disclosed is a hydrocarbon reforming method and a hydrocarbon reforming device which ensure high yield and prolonged lifetime of an oxygen-permeable membrane. In the hydrocarbon reforming method, a partial oxidation reforming reaction using oxygen isolated with an oxygen-permeable membrane and a steam reforming reaction are performed using a hydrocarbon as a starting material to produce a hydrogen-containing gas. In the method, the overheating of the oxygen-permeable membrane can be prevented by removing a Joule heat that is generated during the isolation of oxygen. The energy corresponding to a portion of the Joule heat which is absorbed for the increase in entropy associated with the partial oxidation reforming reaction is utilized as the heat to be adsorbed associated with the steam reforming reaction.
