Abstract

SE DESCRIBE UN CATALIZADOR ACTIVO Y SELECTIVO PARA LA REDUCCION DE LOS OXIDOS DE NITROGENO EN NITROGENO MOLECULAR EN UN MEDIO SOBREESTOEQUIOMETRICO EN OXIDANTES, POR AGENTES REDUCTORES TALES COMO EL MONOXIDO DE CARBONO, EL HIDROGENO, LOS HIDROCARBUROS, LOS ALCOHOLES Y OTROS COMPUESTOS ORGANICOS OXIGENADOS. LA COMPOSICION DE LA FASE ACTIVA DE ESTE CATALIZADOR, EXPRESADA EN PORCENTAJE DE MASA RESPECTO DEL PRODUCTO CALCINADO A 1000 (GRADOS) C DURANTE 4 HORAS (SUSTRATO MONOLITICO EXLUIDO), ES LA SIGUIENTE: - DE 50 A 99,78% DE AL MENOS UN OXIDO INORGANICO REFRACTARIO, - DE 0,1 A 20% DE AL MENOS UN ELEMENTO (A) PERTENECIENTE AL GRUPO DE LAS TIERRAS RARAS, EXPRESADO EN FORMA DE OXIDO, - DE 0,1 A 15% DE AL MENOS UN ELEMENTO (B) PERTENECIENTE AL GRUPO IIA DE LOS ALCALINOTERROSOS, EXPRESADO EN FORMA DE OXIDO, - DE 0,01 A 5% DE AL MENOS UN METAL (C) PERTENECIENTE AL GRUPO DE LOS METALES PRECIOSOS DE LA FAMILIA DEL PLATINO, Y DE 0,01 A 10% DE AL MENOS UN METAL (D) PERTENECIENTE AL GRUPO DE LOS METALESNOBLES, PLATA Y ORO. EN LA PREPARACION DE ESTOS CATALIZADORES, LA IMPREGNACION DE LOS METALES PRECIOSOS (C) ESTA VENTAJOSAMENTE SEGUIDA POR UN TRATAMIENTO TERMICO BAJO ATMOSFERA REDUCTORA.
