Abstract
The invention is a method for demetallating petroleum streams by subjecting a hydrocarbon soluble metals-containing petroleum stream and an aqueous electrolysis medium to a sufficient anodic potential at a pH sufficient to produce a treated petroleum stream having a decreased metals content. The invention is useful for enhancing the value of petroleum streams that traditionally have limited use in refineries due to their content of metals, particularly Ni and V.
