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

摘要

[Objects] To provide a method and an apparatus for reforming a hydrocarbon with a prolonged life of an oxygen-permeable membrane and a high recovery rate.;[Solutions] The oxygen-permeable membrane absorbs the free energy change, ΔG, of a partial oxidation reforming reaction and then converts it into work for oxygen isolation and Joule heat, Q. Here, as seen in Table 1 and Fig. 1, ΔG of the partial oxidation reforming reaction is approximately ten times larger than ΔH, and further increases as the temperature increases. The generated Joule heat, Q, has to be removed at a high efficiency, and this removal process is achieved by returning a portion of the Joule heat to the system as the entropy change, TΔS, of the partial oxidation reaction itself and by steam reforming using the total energy change, ΔH.
