    Abstract: Disclosed is a process and apparatus for recycling flue gas from a regenerator back to the regenerator to provide fluidization gas needs. Catalyst may be separated from the flue gas before recycle and the flue gas may be compressed before recycle to the regenerator. The process and apparatus reduces the size capacity of downstream product recovery equipment by reducing gases derived by oxidation in the process and reduces the potential for after burn in the regenerator.

    Abstract: Systems and methods for regenerating a spent catalyst are provided. The method can include mixing a spent catalyst with a carrier fluid to provide a mixture. The spent catalyst can include carbon deposited on at least a portion thereof. The carrier fluid can include an oxygen containing gas. The mixture can be introduced to or above an upper surface of a dense phase catalyst zone disposed within a regenerator. A gas can be introduced to a lower zone of the dense phase catalyst zone. At least a portion of the carbon deposited on the catalyst can be combusted to provide a flue gas, heat, and a regenerated catalyst.
