Abstract: The processiing of Russian atmospheric residue 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 gum 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.
