Abstract
A process for regenerating catalyst from a fluidized catalytic process is disclosed. The process comprises passing a COoxidation stream to a regenerator in which coke is combusted from catalyst to provide a COrich flue gas stream. The COrich flue gas stream is separated into an underflow stream comprising catalyst fines and a COrich 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.
