Abstract: A process for regenerating catalyst from a fluidized catalytic process is disclosed. The process comprises passing a CO2 oxidation stream to a regenerator in which coke is combusted from catalyst to provide a CO2 rich flue gas stream. The CO2 rich flue gas stream is separated into an underflow stream comprising catalyst fines and a CO2 rich flue gas overflow stream. The overflow stream is separated into a recycle stream and a power recovery stream. The recycle stream of the overflow stream is recycled to the regenerator.
