SPECIFICATION Title of the Invention: PROCESS FOR THE PRODUCTION OF SOLVENT-REFINED COAL USEFUL AS STARTING MATERIAL FOR OTHER CARBONACEOUS PRODUCTS Abstract of the Disclosure: A process is disclosed for the production of solvent-refined coal useful as a starting material for micromosaic carbonaceous products and having an O/C atomic ratio of 0.040 to < 0.046, or useful as a starting material for coarse mosaic carbonaceous products and having an O/C atomic ratio of 0.030 to < 0.040 or useful as a starting material for needle like carbonaceous products and having an O/C atomic ratio of less than 0.030. The process comprises dissolving in a hydrocarbon solvent a coal intrinsically having an O/C atomic ratio of 0.030 to < 0.055 or a coal pre- treated with a solvent, under hydrogen pressure, so as to have an O/C atomic ratio of 0.030 to < 0.055, and heating the resultant coal solution under a pressure of hydrogen for a period of time sufficient to form said solvent-refined coal. -1-
