Abstract
Catalizador para la eliminación de óxidos de nitrógeno en presencia de oxígeno. El objeto de la presente invención es preparar un catalizador que permita la descomposición y/o reducción de los NO{sub,x}, presente en los gases provenientes de cámaras de combustión como los tubos de escape de coches, plantas industriales, etc., sin empleo de amoniaco como agente reductor y manteniendo una elevada actividad en presencia de importantes cantidades de oxígeno. Para ello, se empleará un catalizador que permita la descomposición y/o reducción de los óxidos de nitrógeno, compuesto por una zeolita con una relación molar siO{sub,2}/Al{sub, 2}O{sub, 3} mayor de 15 conteniendo iones cobre, cobalto, platino, paladio u otros metales de transición.Catalyst for the elimination of nitrogen oxides in the presence of oxygen. The object of the present invention is to prepare a catalyst that allows the decomposition and / or reduction of NO {sub, x}, present in the gases from combustion chambers such as car exhaust pipes, industrial plants, etc., without the use of ammonia as a reducing agent and maintaining high activity in the presence of significant amounts of oxygen. For this, a catalyst that allows the decomposition and / or reduction of nitrogen oxides, composed of a zeolite with a molar ratio siO {sub, 2} / Al {sub, 2} O {sub, 3} greater than 15 containing copper, cobalt, platinum, palladium or other transition metals ions.
