Abstract
A process and apparatus for indirect heating of catalyst in the regeneration zone is disclosed. A hot flue gas flows within a heating tube and the catalyst to be heated flows outside the heating tube. The hot flue gas is generated by igniting a fuel stream. The hot flue gas is generated directly in the heating tube or is generated in a separate burner outside the heating tube.
