Abstract: Fluid catalytic cracking（FCC） remains a pivotal process for converting heavy oil into lighter products in China. It has also become essential for refineries aiming to achieve the strategic goal of “reducing gasoline production while increasing chemical product” particularly as gasoline demand approaches its peak. The development of the FCC process is currently facing multiple challenges, including the efficient and deep conversion of feedstocks, the production of green and low-carbon products, and intelligent long-term operation, driven by the heavier nature of feedstocks and the growing demand for lighter products. Focusing on these challenges, China University of Petroleum has continuously optimized and upgraded the FCC process through technological theory innovation, technology theory innovation, process reconfiguration and the implementation of artificial intelligence（AI）＋computational fluid dynamics（CFD） intelligent guarantee. In this paper, emulsified feeding and steam stripping enhancement technology, FCC coking and catalyst loss intelligent prediction and warning technology, and regenerator flus gas CO₂ in-situ enrichment technology are summarized, and an outlook for the further development of the FCC process is presented.
