ABSTRACT:
This invention relates to a method for upgrading heavy oils for use in subsequent hydrocarbon processing. The process is especially suitable for removing metals which are in the form of nickel or vanadium organic compounds and for lowering the Conradson Carbon Residue of the resulting oil. The process includes the steps of diluting the heavy oil with a solvent which completely solvates the oil and subjecting the resulting mixture to an ultrafiltration step using selected membranes.
