Abstract
A method for lowering the viscosity and specific gravity of a heavy hydrocarbon to render it pipelineable is disclosed. The method comprises adding a vanadium and nickel containing coke fly ash to the heavy hydrocarbon; reacting the heavy hydrocarbon in the presence of the fly ash with a molecular hydrogen containing gas under hydroconversion conditions for a time sufficient to lower the viscosity of the hydrocarbon in the range of about 20 to 60 centipoise at 40.degree. C. and to lower the specific gravity in the range of from about 0.925 to about 0.940 at 15.degree. C., whereby the heavy hydrocarbon is rendered pipelineable.
