Abstract

Se proporciona un proceso para regenerar un catalizador de conversion tratado a alta temperatura que se ha desactivado debido al deposito de coque y catalizador que comprende al menos un metal del grupo VIII. El proceso comprende primero quemar el coque del catalizador el poner en contacto el catalizador con un gas contiene oxígeno. El catalizador luego se reduce al poner en contacto el catalizador en un gas reductor, preferentemente hidrogeno. El catalizador luego se trata a una temperatura en el intervalo desde el inventario de 523 degree (975 degree ) a menos de 621 degree C (1150 degree F). Este ultimo paso del tratamiento puede tomar lugar en ya sea una atmosfera de gas inerte. También se prefiere que le ultimo paso se lleve a cabo mientras que se mantiene el nivel de agua del gas afluente por debajo de 200 ppmv.
