Abstract
An FCC reactor and regenerator arrangement provides substantially independent control of temperature on the reactor side and regenerator side of the process. The arrangement withdraws cooled regenerated catalyst for transfer to a reactor riser and cooled regenerator catalyst for return to the regeneration zone. The process may operate with a single cooler that supplies catalyst to both the reaction side of the process and the regeneration side of the process.
