  • Patent number: 9371494
    Abstract: Optimizing low coke naphtha reforming continues to pose significant challenges for oil refining companies in the operation of continuous catalytic regenerative reforming units for economic production of hydrogen, LPG and reformate. A novel processing scheme is hereby disclosed wherein multiple additives are used to increase spent catalyst coke to ensure operating the regenerators in steady state white burn operations. In previous disclosures novel additives sulfur and kerosene were identified as separately imparting enhanced rates of coke formation on the catalysts even at very mild severity catalytic reforming operations. To further accelerate spent catalyst coke formation and derive benefits from synergistic use of sulfur and kerosene, it is suggested that both sulfur and kerosene be used as additives in combination or in series with sulfur added first followed by kerosene and vice versa.
