A process is described for the production of high grade carbonaceous binders, wherein an aromatic high grade carbonaceous material is produced from 5-40% by weight of reduced or low ash coal or similar carbon containing raw materials by treatment with 20-80% by weight of high-boiling aromatic solvents, derived from coal, and 15-50% by weight of high-boiling aromatic solvents, derived from mineral oil, at temperatures of 300 DEG -420 DEG C. and for a reaction period of 1-4 hours, at a reaction pressure of up to 50 bar, and is optionally freed from low-boiling components. |
