Method of solvent extraction of coal by a heavy oil

Patent ·
OSTI ID:6681110
A solid carbonaceous material, such as coal, is converted to liquid products and the asphaltene content of a heavy hydrocarbonaceous liquid is reduced in the process wherein the solid is solvent extracted by the heavy hydrocarbonaceous liquid and a hydrocarbonaceous recycle stream with a finely divided, unsupported metal catalyst and the resultant mixture of liquids is recovered as the product.
