ABSTRACT:
A method of catalyst manufacture. A calcined tin-containing refractory inorganic oxide support or carrier material is impregnated with an acidic solution of a precursor compound of a platinum group metal and a precursor compound of an iron group metal. The impregnated carrier material is dried over an extended period to reduce the volatile content thereof to less than about 15 wt. % prior to high temperature calcination. Drying the impregnated carrier material in accordance with the present invention provides a catalyst substantially improved in activity stability.
