SYSTEMS AND METHODS FOR REGENERATING A SPENT CATALYST |
摘要 |
Systems and methods for regenerating a spent catalyst are provided. The method can include heating a hydrocarbon and a coke precursor in the presence of catalyst particles to provide a cracked hydrocarbon product and coked catalyst particles. The cracked hydrocarbon product and the coked catalyst particles can be selectively separated to provide a hydrocarbon product and coked catalyst particles. The coked catalyst particles can be mixed with a carrier fluid to provide a mixture. The mixture can be introduced to an upper surface of a dense phase catalyst zone disposed within a regenerator. A gas can be introduced to a lower zone of the dense phase catalyst zone. At least a portion of the carbon deposited on the coked catalyst particles can be combusted to provide a flue gas, heat, and a regenerated catalyst. |
