摘要

SPECIFICATIONTitle of the Invention:PROCESS FOR THE PRODUCTION OF SOLVENT-REFINED COAL USEFUL ASSTARTING MATERIAL FOR OTHER CARBONACEOUS PRODUCTSAbstract of the Disclosure:A process is disclosed for the production of solvent-refinedcoal useful as a starting material for micromosaic carbonaceousproducts and having an O/C atomic ratio of 0.040 to 0.046, oruseful as a starting material for coarse mosaic carbonaceousproducts and having an O/C atomic ratio of 0.030 to 0.040 oruseful as a starting material for needle like carbonaceous productsand having an O/C atomic ratio of less than 0.030. The processcomprises dissolving in a hydrocarbon solvent a coal intrinsicallyhaving 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 anO/C atomic ratio of 0.030 to 0.055, and heating the resultantcoal solution under a pressure of hydrogen for a period of timesufficient to form said solvent-refined coal.-1-
