    • 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.
    • 将蒸汽(25)加入到通过失活的焦化催化剂的致密床的空气中。 蒸汽通过除去吸附的重质烃并与焦炭反应产生一氧化碳。 总体效果是通过去除可氧化材料并通过吸热反应将焦炭转化为一氧化碳和氢气来降低再生器温度。 这允许在较高的康拉逊碳供应(10-14%康拉逊碳)下操作。 在下部再生器(34)的底部添加空气(42),并且另外的空气入口被放置在下部再生器部分的上部。
