Abstract
A catalyst for reforming CH.sub.3 OH to H.sub.2 and CO, which is high in activity, selectivity and durability. The catalyst uses a granular or monolithic carrier which is made of active alumina at least in its surface regions, and compound oxide(s) of perovskite structure MAlO.sub.3, where M is a metal selected from the rare earth elements, e.g. La or Ce, or from the titanium family elements, e.g. Ti or Zr, and catalytic metal(s) of the platinum group, e.g. Pt, Pd and/or Rh, are deposited on the carrier. Preferably the amount of the metal(s) M in the compound oxide(s) is 0.1-10.0 Wt % of the carrier, and the content of the metal(s) of the platinum group in the catalyst is 0.1 to 1.0 Wt %. The catalyst is prepared by first depositing the compound oxide(s) on the carrier by pyrolysis of suitable salts of the respective metals M and Al which are applied to the carrier as a mixed solution, and then depositing the catalytic metal(s) by pyrolysis of suitable compound(s) of the catalytic metal(s) applied to the carrier as a solution.
