Abstract

AL INTRODUCIR AIRE EN UNA DEPURACION CATALITICA Y A CONTINUACION EN UN SISTEMA DE RECTIFICACION SE OBTIENE UN PRODUCTO DE ALTA PUREZA. EN LA DEPURACION CATALITICA, EL AIRE DE ENTRADA PASA POR UNA CAPA CATALITICAMENTE ACTIVA. LA DIMENSION DE LA CAPA CATALITICA EN EL SENTIDO LONGITUDINAL DE LA CORRIENTE ES COMO MINIMO DIEZ VECES MENOR QUE EN EL SENTIDO TRANSVERSAL DE LA CORRIENTE.
