Abstract of the Disclosure A process for producing a high-temperature resistant honeycomb catalyst, which comprises admixing cerium, zirconium, at least one metal selected from the group consisting of iron and nickel, at least one metal selected from the group consisting of platinum, palladium and rhodium, and optionally at least one metal selected from the group consisting of neodymium, lanthanum and praseodymium, each in the form of an aqueous solution or dispersion of a soluble or easily water-dispersible compound of the metal, with active alumina, drying the mixture, calcining it, dispersing the resulting catalyst composition in an aqueous medium, and depositing the dispersion on a monolithic honeycomb carrier. The resulting catalyst is useful for simultaneous conversion of hydrocarbons, carbon monoxide and nitrogen oxides in an exhaust gas.
