Abstract
A catalyst for reforming of methanol to hydrogen and carbon monoxide, which is high in activity, selectivity and durability. The catalyst utilizes a granular or monolithic carrier of which the principal material is active alumina. First the carrier is coated with a mixture of cerium oxide and zirconium oxide, preferably by pyrolysis of a cerium salt and a zirconium salt applied to the carrier as a mixed solution. Then either Pt or Pd, or both, is deposited on the coated carrier preferably by pyrolysis of a platinum or palladium compound applied to the carrier as a solution. After that the nearly finished catalyst is treated with a solution of a reducing agent such as sodium boron hydride or hydrazine to render the deposited Pt and/or Pd substantially completely reduced.
