Abstract
Catalysts adapted to catalyse the oxidation of carbon monoxide to carbon dioxide comprise palladium, one or more of the metals platinum, ruthenium, rhodium and iridium and one or more of the metals copper, nickel, cobalt, iron, manganese, silver, lanthanum, cerium, praseodymium and neodymium on substantially chloride-free stannic oxide supports.
Claims7
A catalyst for catalyzing the oxidation, in the presence of oxygen, of carbon monoxide to carbon dioxide, said catalyst being substantially chloride-free and consisting essentially of stannic oxide supporting a mixture of (i) palladium, (ii) at least one member of the group consisting of platinum, ruthenium, rhodium and iridium and (iii) at least one metal selected from the group consisting of copper, nickel, cobalt, iron, manganese, silver, lanthanum, cerium, praseodymium and neodymium, said catalyst being suitable for use at ambient or sub-ambient temperature and being characterized by enhanced activity for said oxidation and reduced proneness to deactivation in service by the incorporation therein of (ii) and (iii).
