Abstract

La presente invención se refiere a una composición catalizadora de óxido mixto, de metal no precioso, para la oxidación catalítica de las emisiones de gas de escape que salen de las máquinas de función interna y que comrpende cantidades de monóxido de carbono catalíticamente oxidables e hidrocarburos no quemados, caracterizada porque contiene los óxidos mixtos de estaño tetravalente (SnO2), cromo hexavalente (CrO3) y cobre divalente (CuO) en proporciones que proveen una producción en peso de SnO2:CrO3 en la escala de 99:1 a l:99 y una cantidad de óxido de cobre (CuO) que es de 0.5 a 100 por ciento en peso, con base en el peso combinado de SnO2 y CrO3.
