Abstract (en)
Steam (25) is added to the air that passes through the dense bed of the deactivated coked catalyst. Steam acts by removing adsorbed heavy hydrocarbons and reacting with the coke to yield carbon monoxide. The overall effect is to lower the regenerator temperature by removing oxidizable material and convert coke to carbon monoxide and hydrogen via endothermic reaction. This allows operation at higher Conradson carbon feed (10-14% Conradson carbon). Air (42) is added at the bottom of the lower regenerator (34) and also an additional air inlet is placed in the upper part of the lower regenerator section.
