摘　　要：介绍了俄罗斯原油常压渣油在中国化工集团大庆中蓝石化有限公司催化裂化装置的工业应用情况。该常压渣油硫含量高,密度高,胶质、沥青质含量高,因此催化裂化加工难度大,焦炭产率高,平衡剂重金属含量高。针对原料油的加工特点,进行了装置关键部位的材质升级,并针对汽油辛烷值降低等变化采取了相应的措施,保证了装置在原料变化前后的平稳过渡。The processing of atmospheric residue from Russian crude in FCC unit of Daqing Zhonglan Petrochemical Company was introduced.Catalytic cracking of the Russian AR is difficult because of its high sulfur content,high density,high content of resin and asphaltene,leading to high coke yield and more metal on the equilibrium catalyst.In view of this concern,the material upgrade of the key parts of the device was conducted and corresponding measures were taken to improve the gasoline octane number.A stable transition before and after raw material changes is guaranteed.
