Disclosed is a process for the upgrading and demetallizing of heavy oils and bitumens. A crude heavy oil and/or bitumen feed is supplied to a solvent extraction processwherein DAO and asphaltenes are separated. The DAO is supplied to an FCC unithaving a low conversion activity catalyst for the removal of metals contained therein. The demetallized distillate fraction is supplied to a hydrotreaterfor upgrading and collected as a synthetic crude product stream. The asphaltene fraction can be supplied to a gasifierfor the recovery of power, steam and hydrogen, which can be supplied to the hydrotreateror otherwise within the process or exported. An optional coker unitcan be used to convert excess asphaltenes and/or decant oil to naphtha, distillate and gas oil, which can be supplied to the hydrotreater

Process for upgrading heavy oil and bitumen

Disclosed is a process for the upgrading of heavy oils and bitumens, where the total feed to the process can include heavy oil or bitumen, water, and diluent. The process can include the steps of solvent deasphaltingthe total feedto recover an asphaltene fraction, a deasphalted oil fractionessentially free of asphaltenes, a water fraction, and a solvent fraction. The process allows removal of salts from the heavy oils and bitumens either into the aqueous products or with the asphaltene product.
