摘要: Improved method for solubilizing solid carbonaceous materials, e.g., wood and/or coal in an aromatic petroleum or coal-derived solvent in the presence of alkali and hydrogen transfer agent at elevated temperatures. The liquid products can be used as fuels or further processed into desirable products.
