Abstract
A method for preparing an oil soluble catalytic precursor includes the steps of: providing a mixture of a catalytic metal salt in water, wherein the catalytic metal salt contains a catalytic metal selected from the group consisting of alkali metals, alkaline earth metals, transition metals, and mixtures thereof; providing a heavy hydrocarbon phase; forming a water in oil emulsion of the mixture in the heavy hydrocarbon phase; and heating the emulsion at a temperature sufficient to dehydrate the emulsion so as to provide a hydrocarbon containing an oil soluble compound containing the catalytic metal.
