The present invention relates to a reforming catalyst by sulfur poisoning or carbon deposition even in a steam reforming reaction at a low temperature in the case of producing hydrogen using a petroleum hydrocarbon containing a heavy and difficult-to-desulfurize sulfur compound as a raw fuel. , A steam reforming catalyst capable of effectively producing hydrogen by suppressing adverse effects on the reformer and the unit located downstream thereof, shortening the start-up time required to start hydrogen production, and the catalyst A method for producing hydrogen was provided. A steam reforming catalyst in which a rare earth metal is contained in an alumina support and a noble metal component containing at least one of ruthenium, rhodium, and platinum is supported, and the noble metal component content (% by mass) contained in the catalyst; A reforming catalyst for hydrogen production, wherein the product of the precious metal component dispersity (%) is 100 or more and the precious metal component dispersity (%) is 70% or less. And a method for producing hydrogen from a fuel oil for producing hydrogen using this catalyst. [Selection figure] None |
