Disclosed is a process for the upgrading and demetallizing of heavy oils and bitumens. Acrude heavy oil and/or bitumen feed is supplied to a solvent extraction process (104)wherein DAO and asphaltenes are separated. The DAO is supplied to an FCC unit (106)having a low conversion activity catalyst for the removal of metals containedtherein. The demetallized distillate fraction is supplied to a hydrotreater (110)for upgrading and collected as a synthetic crude product stream. The asphaltene fractioncan be supplied to a gasifier (108) for the recovery of power, steam and hydrogen,which can be supplied to the hydrotreater (110) or otherwise within the processor exported. An optional coker (234) can be used to convert excess asphaltenesand/or decant oil to naphtha, distillate and gas oil, which can be supplied tothe hydrotreater (220). |
