ABSTRACT:
Alumina supported platinum-group metal pelleted catalysts are made which exhibit excellent performance and which have unique Pt concentration profiles. The catalysts are doubly promoted with ceria and alkali metal oxides, especially ceria along with lithia, and can optionally have nickel (oxide) as a base metal catalytic ingredient. The unique Pt profile is obtained by adding at least part of the Rh component separately from any other Pt group metals.
