Abstract

Se describe un proceso de tratamiento de alta temperatura para incrementar la conversion y reducir la velocidad de ensuciamiento de los catalizadores de conversion. El proceso comprende reducir el catalizador de una atmosfera de gas reductor a una temperatura por abajo de 552 degree C (1025 degree F) y luego tratar el catalizador reducido a una temperatura desde 552 degree C (1025 degree F) hasta 629 degree C (1275 degree F) en una atmosfera de gas inerte.
