ABSTRACT:
A catalyst of the perovskite-type ABO.sub.3 crystal structure with from about 1 up to about 20 percent of the B cation sites occupied by rhodium ions and the remainder of the B cation sites occupied by ions consisting essentially of cobalt and the A cation sites occupied by lanthanide ions of atomic number 57 to 71 and ions of at least 1 metal of Groups IA, IIA or IVA of the Periodic Table having ionic radii of about 0.9 A to 1.65 A, and proportioned so that no more than 50 percent of the cobalt ions are tetravalent and the remaining cobalt ions are trivalent. The above-described catalyst on a refractory support. A method for producing hydrogen by reacting hydrocarbon in the presence of a catalyst as described above, either with or without a refractory support, by partial oxidation or steam reforming.
