Abstract

Abstract: The FCC feedstock quality of Zhenhai Refinery & Chemical Company has been declined since 2005. In this paper problems occurred during processing inferior feedstocks, such as high nickel and high acid vacuum residue (VR), high vanadium VR, high sodium VR, high sulfur VR and high density VGO, are analyzed and optimization measures for a safety and stable long-term running are summarized.

Key words: catalytic cracking, feedstock, inferior quality, optimization
