Abstract: In the long run, the crude oil would become heavier and poorer in quality. Hydrocracking technologies are regarded as one of the key techniques in efficient and clean conversion of residuum, and have become a major upgrading process in the refineries. In this paper, the application status of residuum ebullated bed and slurry bed hydrocracking technologies were introduced. The technical characteristics and technical-economic indicator were also compared. And then, the new progress and future trend were reviewed. The ebullated bed technology is the most mature residuum high-efficient conversion technology currently, and will continue to play an important role in residuum utilization. In the future, the research is focused on combined technology and unconverted tail-oil processing technology. Although the slurry bed technology is far from mature compared with ebullated bed technology, it has its advantage of high conversion rate and great potential for future development. The technology development should resolve equipment coking problem and develop high-active and high-dispersible catalyst.
