Abstract

SE FACILITA UNA COMPOSICION DE CATALIZADOR DE ZEOLITA EN LA CUAL UNA ZONA PRIMERA O CORRIENTE ARRIBA DEL CATALIZADOR TIENE UNA CARGA DE SUSTANCIA ACTIVADORA DE LOS CATALIZADORES DE METAL INFERIOR (ES DECIR, HIERRO O COBRE), QUE LA CARGA DE SUSTANCIA ACTIVADORA DE LOS CATALIZADORES DE METAL DE LA ZONA SEGUNDA O CORRIENTE ABAJO DEL CATALIZADOR. LA PRIMERA ZONA PUEDE CONTENER DESDE NADA HASTA APROXIMADAMENTE EL 1 POR CIENTO DEL PESO DE LA SUSTANCIA ACTIVADORA Y LA SEGUNDA ZONA PUEDE CONTENER DESDE APROXIMADAMENTE 1 AL 30 POR CIENTO DE PESO DE LA SUSTANCIA ACTIVADORA. LA ZEOLITA PUEDE SER CUALQUIER ZEOLITA APROPIADA, ESPECIALMENTE UNA QUE TENGA UNA RELACION DE SILICE A ALUMINA DE APROXIMADAMENTE 10 O MAS, Y UN TAMAÑO DE PORO CINETICO DE APROXIMADAMENTE 7 A 8 ANGSTROMS, TENIENDO LOS POROS CITADOS INTERCONECTADOS EN TODAS LAS TRES DIMENSIONES CRISTALOGRAFICAS. EL METODO DEL INVENTO PROPORCIONA EL PASO DE UNA CORRIENTE GASEOSA QUE CONTIENE OXIGENO, OXIDOS DE NITROGENO Y AMONIACO SECUENCIALMENTE ATRAVES DEL PRIMER Y SEGUNDO CATALIZADOR COMO SE DESCRIBE MAS ARRIBA, FAVORECIENDO EL PRIMER CATALIZADOR LA REDUCCION DE OXIDOS DE NITROGENO Y FAVORECIENDO EL SEGUNDO CATALIZADOR LA OXIDACION U OTRA DESCOMPOSICION DEL EXCESO DE AMONIACO.
