Abstract
Enhancement of the overall conversion efficiency from CH4 to H2 using a permeable-membrane Ni tube and temperature rise by a chemical heat pump system packed with hydrogen-absorbing alloys have been investigated in order to produce H2 more efficiently using a high-temperature heat source. The two feasibilities to enhance the conversion efficiency are tested using their respective experimental apparatuses. Two things are experimentally proved that (1) Ni permeable-membrane tubes can provide measures to convert CH4 to H2 continuously without any deterioration in the course of partial oxidation or steam reformation and (2) two Zr(V1âxFex)2 alloys with different Fe displacement ratios can comprise a chemical heat-pump system working at higher-temperature conditions.
