Abstract

UNA UNIDAD CATALIZADORA ESTA CONSTRUIDA POR APILAMIENTO DE ELEMENTOS CATALIZADORES RECTANGULARES (1) FORMADOS POR EL CORTE DE PLANCHAS DE SOPORTE DE CATALIZADOR CUBIERTAS CON UN MATERIAL CATALIZADOR Y QUE TIENE ENERVADURAS (2) INCLINADAS 45 SPECTO AL BORDE DE UNA CARA ESPECIFICADA (1A) DE CADA UNA DE ELLAS, Y ESAS GIRADAS CARA ARRIBA O ABAJO SEGUN EL CASO, Y LA UNIDAD CATALIZADORA ESTA COLOCADA EN UN PASO DE GAS CON LOS ENERVADURAS (2) DE LOS ELEMENTOS CATALIZADORES (1) INCLINADO UN ANGULO MAYOR DE 0 GAS (6). CUANDO LA UNIDAD CATALIZADORA CONSTA DE ELEMENTOS CATALIZADORES (1) CUBIERTOS CON UN CATALIZADOR DESNITRIFICANTE COLOCADO EN EL PASO DEL GAS, LAS ENERVADURAS (2) DE LOS ELEMENTOS CATALIZADORES (1) BLOQUEAN EL FLUJO DE GAS (6) Y GENERAN CORRIENTES TURBULENTAS SOBRE LA CARA SUPERIOR DE ELLA PARA PROMOVER EL CONTACTO DEL AMONIO Y EL NO{SUB,X} CONTENIDO EN EL GAS DE ESCAPE CON EL CATALIZADOR. CUANDO EL FLUJO DE GAS (6) SE PERTURBA, EL ESPESOR DE LA PELICULA LAMINAR QUE CUBRE LA SUPERFICIEDE LOS ELEMENTOS (1) SE REDUCE, PARA QUE EL AMONIO Y EL NO{SUB,X} PUEDAN SER FACILMENTE DIFUNDIDOS Y LA ACTIVIDAD DEL CATALIZADOR PUEDA SER AUMENTADA. LOS ELEMENTOS CATALIZADORES MUESTRAN SUS HABILIDADES EFECTIVAMENTE SIN TRANSMITIR PERDIDA DE PRESION SIGNIFICATIVA EN EL FLUJO DE GAS.
