Abstract: Thermal crackings of KWTVR and YZVR were each investigated by autoclave with hydrogen and catalyst at 460 ℃, shorter residence time and 425 ℃, longer residence time. The results show that the thermal cracking is the primary reaction in the residue thermal conversion in hydrogen. For the same kind of residue and at similar conversion, the sulfur and nitrogen removal rates of gasoline and diesel, and alkanes yield are all lower, while the yield of toluene insoluble is higher at conditions of high cracking temperature and shorter residence time, compared with lower temperature and longer residence time.
