Patent

CA 2242519

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°C and to lower the specific gravity in the range of from about 0.925 to about 0.940 at 15°C, whereby the heavy hydrocarbon is rendered pipelineable.
