Abstract

Se describe un método que permite reemplazar un catalizador del interior de una columna de reaccion catalítica, siempre operando la reaccion catalítica en el curso de la cual se deriva el fluido esencialmente monofásico, de tal manera que se evite su paso a través del catalizador, evacuando de la columna el catalizador que ha perdido al menos una parte de sus propiedades, introduciendo una cantidad de catalizador sensiblemente igual a la cantidad de catalizador descargado, y restableciendo la circulacion de la fase esencialmente monofásica a través del producto.
