Abstract

UN METODO PARA REGENERAR UN CATALIZADOR DE FLUORINACION USADO, TAL COMO UN COMPUESTO CONTENIENDO CROMO, COMPRENDE EL PONER EN CONTACTO EL CATALIZADOR UTILIZADO A UNA TEMPERATURA DE 300 C A 500 C CON UNA MEZCLA DE UN AGENTE DE OXIDACION, ESPECIALMENTE AIRE, Y FLUORURO DE HIDROGENO Y OPCIONALMENTE UN DILUYENTE INERTE TAL COMO NITROGENO, DICHA MEZCLA CONTIENE HASTA UN 30% DE AGENTE DE OXIDACION EN UNA BASE MOLAR. EL METODO EVITA LA PERDIDA DE CROMO DURANTE LA REGENERACION Y REFLUORINACION DEL CATALIZADOR GASTADO, Y PROPORCIONA FLUORURO DE HIDROGENO CALENTADO PARA USARLO DIRECTAMENTE EN REACCIONES DE FLUORINACION.
