Abstract: Challenges facing global refining industry include growing oil demand，inferior crude oil supply，strict product specifications and unconventional oil utilization. Residuum hydroprocessing technologies are crucial to realize clean and efficient conversion of residuum，and have become a major upgrading process in the refineries to meet the challenges. The development status and future trend of fixed bed，ebullated bed and slurry bed processes are discussed. The residuum fixed bed hydrotreating-fluid catalytic cracking combined technology would be the key developing process in the medium term and long term. The ebullated bed technology should resolve the problems of high investment and operating difficulties. The slurry bed technology has its unique advantage，and also great potential for future development.

Key words: residuum, hydrogenation technology, fixed bed, ebullated bed, slurry bed
