ABSTRACT:
A method for continuously or semi-continuously regenerating reforming catalyst by the recirculation of a gas stream advantageously controls the water content by using an oxygen-deficient makeup gas stream to supply the oxygen for combustion of coke. The volume of makeup gas entering the process is increased by reducing its oxygen concentration so that additional waste gases from the combustion of coke on the catalyst can be vented. The venting of additional gas from the circulating gas stream lowers the overall water concentration during the combustion of coke. The oxygen-deficient makeup gas stream can be supplied by oxygen and nitrogen separation from air. Where the production of the oxygen-deficient makeup gas stream also produces an oxygen-enriched stream, the oxygen-enriched stream is advantageously added to a catalyst reconditioning step for an increased dispersion of metals in the catalyst.
