PROBLEM TO BE SOLVED : To provide a steam-reforming catalyst which suppresses adverse affects on reforming catalysts, reformed containers, and units positioned downstream of them due to sulfur poisoning and carbon deposition even in a steam-reforming reaction at low temperatures when hydrogen is manufactured using petroleum carbon hydride containing sulfur compounds that is difficult to desulfur due to their heaviness as raw fuel, and enables the effective manufacturing of hydrogen by shortening the starting time required for the start of the hydrogen manufacture, and a hydrogen manufacturing method using the catalyst. SOLUTION : The reforming catalyst for manufacturing hydrogen is characterized in that the product of a noble metal component dispersion degree(%) and a noble metal component content(mass%) contained in the catalyst is 100 or more and the noble metal component dispersion degree(%) is 70% or less in the steam-reforming catalyst produced by allowing an alumina carrier to contain a rare earth metal and to support a noble metal component containing at least one of ruthenium, rhodium, and platinum. The method of manufacturing hydrogen from fuel oil for manufacturing hydrogen using the catalyst is provided. COPYRIGHT : (C)2010, JPO&INPIT
