Abstract
Upgrading technology for heavy residue in which sulfur and metals are concentrated is getting more important since crude oils tend to be heavier. In this paper, first characteristics of heavy crude oil are explained, then technologies of residue desulfurization and fluid catalytic cracking in refinery are introduced. Especially, HS-FCC technology, which Nippon oil Co., Saudi Arabia and JCCP are under developing, is focused on as a new technology. Finally, the effect of heavy crude oil on the production of clean fuels is discussed and a promising way to produce clean fuels from heavy residue is proposed.
