▎ 摘  要

NOVELTY - The method involves subjecting the coal (1) to a dissolution process to produce a solubilized coal material. The solubilized coal material is subjected to a pyrolysis process to produce the high conductivity carbon material. The dissolution process includes adding reagents, solvents and catalysts to the coal. The dissolution process produces a mineral fraction (6) in addition to the solubilized coal material. The pyrolysis process includes a gas combustor for applying heat to the solubilized coal material. USE - Method of producing high conductivity carbon material from coal feedstock and processes to produce graphitic carbon-based materials from coal pose challenges associated with the chemical modifications of the native coal carbon structures. ADVANTAGE - The coal dissolution processes can be optimized to produce solubilized coal materials with high yields. The pyrolytic processes produce gaseous byproducts that can be used as low emission fuels. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart that illustrates the primary steps associated with the production of graphene-like, high conductivity carbon material from coal.
