摘　　要：基于催化裂化再生器主风分布器的设计方法与经验 ,对中国石油化工股份有限公司荆门分公司催化裂解装置二密相床主风分布器进行了改造设计。装置运行结果表明 ,改造后不但降低了分布器压力降和催化剂的跑损 ,保证了二密床层均匀流化 ,而且解决了由于再生斜管流动不畅而导致的催化剂输送故障。为装置的节能降耗及长周期运转打下了坚实的基础。Main air distributor of the second dense bed in FCC unit of Jingmen Company (China Petrochemical Corporation) has been revamped on the basis of the design method and experience for the main air distributor of regenerator in FCC unit. Running result shows that the pressure drop of the distributor and the catalyst loss have been decreased, even fluidization in second dense bed is well obtained, and the catalyst transfer stoppage caused by hitched catalyst flow in regenerator inclined tube has been solved. It has laid a good foundation for energy conservation and long period running of the unit.
