【Task】 When Ni—La—Pt / SiO 2 containing platinum is used among the noble metals, the ammonia conversion is about 20% at SV = 1200h−1,400 ° C., and the equilibrium conversion of ammonia reaches almost 100%. In the case of hydrogen production reaction in a small fuel cell, etc., this ammonia reforming is highly active at 400 ° C, and the reformer is repeatedly started and stopped. The catalyst which can manufacture is provided. A support made of one or more rare earth oxides of praseodymium oxide, lanthanum oxide, and cerium oxide, and an ammonia reforming catalyst that is supported on the support and contains ruthenium. An ammonia reforming catalyst further containing an alkali metal of cesium, rubidium, potassium, or sodium. A method for producing hydrogen by reforming ammonia using these catalysts to produce hydrogen and nitrogen. [Selection] Figure 1 |
