<P>PROBLEM TO BE SOLVED: To provide a hydrocarbon reforming apparatus with which a large amount of high purity hydrogen gas can be produced at a lower cost by lowering the decomposition temperature of a hydrocarbon gas and high purity carbon fine powder can be obtained as a by-product. <P>SOLUTION: In the hydrocarbon reforming apparatus, a catalyst obtained by kneading, forming and firing 1-45% silicon dioxide, 10-50% corundum, and 5-30% dolomite-periclase, is heated at 400-800°C in a closed apparatus, then a hydrocarbon gas is brought into contact with the catalyst, and hydrogen gas and the carbon powder are continuously produced from the resulting gas by alternately using biserial cyclones. <P>COPYRIGHT: (C)2008,JPO&INPIT |
