Abstract
A heavy crude oil is fractionated into at least three liquid fractions which include a distillate fraction boiling in the 400.degree. F.-650.degree. F. range and a 650.degree. F.+ boiling range residuum. The distillate cut is hydrodesulfurized and the residuum is hydrodemetallized. The cuts thus hydrotreated, and at least a part of the third liquid fraction, are then combined to form an upgraded synthetic crude oil of relatively low sulfur content and relatively low vanadium and nickel content.
