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.
