Abstract
A process for combusting coke from catalyst in partial burn mode is disclosed. The regenerator comprises two chambers. The bulk of the combustion is performed in a first chamber. Disengagement of the catalyst from gas is conducted in the second chamber. Heated gas with a low fraction of oxygen fluidizes catalyst in the second chamber.
