Abstract

UN PROCEDIMIENTO PARA LA REGENERACION DE UN CATALIZADOR ZEOLITICO DE GRAN TAMAÑO DE POROS QUE HA SIDO DESACTIVADO MEDIANTE LA FORMACION DE AGLOMERADOS DE METALES DEL GRUPO VIII SOBRE LA SUPERFICIE DEL CATALIZADOR. EN EL PROCEDIMIENTO, SE REDISPERSAN LOS AGLOMERADOS DE METALES DEL GRUPO VIII PARA PRODUCIR AGLOMERADOS DE PEQUEÑO TAMAÑO. EL PROCEDIMIENTO COMPRENDE UNA ETAPA DE OXICLORACION, UNA ETAPA DE PURGADO CON NITROGENO Y UNA ETAPA DE REDUCCION.
