Utilization of heavy crude including unconventional oil may be indispensable to cope with an increasing demand of crude oil in developing countries, such as China and India. Upgrading technologies and processes are, therefore, important for utilizing such heavy oils. In the present paper, upgrading technologies of carbon rejection and hydrogen addition processes are reviewed. Coking and SDA are focused as carbon rejection process. Hydrogen thermal cracking process based on slurry technology is focused as hydrogen addition process. Characteristics of such processes and possibility for integration of SDA and hydrogen thermal cracking are presented.
