<P>PROBLEM TO BE SOLVED: To provide a mixed catalyst having high catalytic ability compared with those of the priority art and maintaining high catalytic ability even when especially using the catalyst. <P>SOLUTION: The mixed catalyst contains: a catalyst A having an active metal α on a surface of a carrier comprising Ba, Al, Zr and those oxides as principal components; and a catalyst B having an active metal β on a surface of a carrier b comprising a cerium oxide as a principal component. The ratio of the mass of the catalyst A to the total mass of the catalyst A and the catalyst B, which is (A/(A+B)×100), is >10 mass% and <80 mass%. <P>COPYRIGHT: (C)2013,JPO&INPIT |
