A methanol reforming catalyst containing passivated copper and zinc oxide and/or
alumina can be prepared by
- (1) precipitating or spray-drying a mixture of catalyst precursor components
dissolved or suspended in a diluent in order to form a solid catalyst precursor
in the form of powder or granules,
- (2) calcining and reducing the solid catalyst precursor obtained in
stage (1),
- (3) passivating the reduced catalyst precursor obtained in stage (2) and
- (4) shaping the passivated catalyst precursor obtained in stage (3)
to form the catalyst.
A reduction in the volume shrinkage and an increase in the mechanical hardness
during operation of the methanol reforming catalyst are achieved by the preparation process.
