摘　　要：叙述了新型与常规相结合的组合式再生剂冷却技术在加工不同的原料、不同产品方案的催化裂化装置上应用前景的研究。通过热平衡计算与反应动力学模拟,采用该技术可以有效地降低再生剂的混合温度,提高剂油比,为改善产品分布和提高经济效益创造了条件。组合式再生剂冷却技术可以在组合模式与常规模式之间灵活地转换。Combined regenerated catalyst cooling is a new tech- nology that can be used in fluid catalytic cracking.It can in- crease the catalyst to oil ratio by lowering the regenerated cata- lyst temperature to improving product distribution and can be switched from and to normal catalyst cooling mode in order to get maximum benefit.The adaptability of combined regenerated catalyst cooling to different type of FCCU is analyzed by simula- tion and heat balance calculation.The application prospects of the said technology are discussed from a technical and economi- cal point of view.
