ABSTRACT:
A regenerator control system is disclosed which is particularly useful in connection with combustion promoted cracking catalysts. The air flow is controlled responsive to the temperature in the dilute phase, first in a direct mode when the amount of combustibles on the catalyst is at or above a set point and second in accordance with a reverse mode when the amount of combustibles is below such a set point. This versatile control system allows a safe operation of a regenerator under a variety of conditions.
