The petroleum refining industry has been required to upgrade more and more heavy oil efficiently, especially the vacuum residua with the decrease of light fraction content in crude oils and the great increase of the demand for light fuel oils, such as gasoline and diesel oil. Residua catalytic cracking process has been developed extremely for recent more than one decade as a major technology to upgrade heavy oil. A number of novel technologies have been developed successfully in heavy oil Catalytic Cracking progress. The latest evolutions of heavy oil catalytic cracking technologies, such as, millisecond catalytic cracking technology, down flow reactor technology, two-stage riser catalytic cracking technology, the new catalytic cracking technology of producing more light olefins, the new catalytic cracking technology of FCC gasoline to decrease olefins, were introduced in this paper.
