Abstract
A catalyst for reforming of methanol to hydrogen and carbon monoxide, which is high in activity, selectivity and durability. The catalyst comprises a granular or monolithic carrier which is made of active alumina at least in its surface regions, at least one metal oxide selected from oxides of the rare earth metals such as Ce, La, Pr, Nd and Y or from oxides of the titanium family metals such as Ti and Zr deposited on the carrier and at least one catalytic metal of the platinum group such as Pt, Rh and/or Pd, which is deposited on the carrier by pyrolysis of suitable compound of each catalytic metal applied to the carrier as a solution and rendered substantially completely reduced by a subsequent treatment with a solution of a reducing agent such as sodium boron hydride or hydrazine. The metal oxide(s) can be deposited on the carrier by pyrolysis of a suitable salt of the selected metal initially applied to the carrier as a solution.
