ABSTRACT:
A petroleum oil containing, in parts by weight, at least 10 parts of vanadium and/or nickel per million parts of the oil is upgraded by contacting the oil in the liquid phase with an aqueous solution of at least one extraction agent of the group ferric salts soluble in acidified water and stannic chloride. The aqueous solution must have a pH at least sufficiently acidic to inhibit precipitation of the agent as hydroxide or basic salt.
