Abstract: A process is described for bringing ground coal or similar carbon-containing raw materials into solution with aromatic solvents under elevated pressure and at elevated temperature. The solvents used are high-aromatic residues obtained from the pyrolysis of petroleum fractions, having an average boiling point of above 380.degree. C., and/or high-aromatic distillates from the pressure/heat treatment of coal tar pitch, having an average boiling point of above 380.degree. C., as well as from 5 to 30% of aromatic products or mixtures of aromatic products, having a boiling point of below 250.degree. C.

Abstract: A process is disclosed for the production of hydrogenated aromatic compounds and mixtures thereof by thermal treatment of aromatic oils or mixtures, derived from coal or petroleum, wherein the improvement over the prior art resides in thermally treating aromatic oils of boiling range 280.degree.-450.degree. C., with residues from the processing of liquid coal conversion products and/or petroleum refining, for up to 10 hours in a temperature region between 200.degree. and 380.degree. C. and at a pressure of maximum 15 bar, with good inter-mixing of the reaction components, and thereafter separating the products by distillation from the pitch-like residue.

Abstract: A process for the production of a highly aromatic pitch-like hydrocarbon by disintegration of comminuted coal or similar carbonaceous raw material with hydrocarbon mixtures as solvent at elevated temperature and pressure.

Abstract: Upgrading coke quality of coals by adding a pitch-like product with a softening point (K-S) of 90.degree.-160.degree. C. to the coal. The additive is obtained by treating finely divided coal or other carbon containing raw material with hydrocarbon solvents derived from coal and petroleum and then removing 2-20% of the light boiling components of the highly aromatic pitch-like product.

Abstract: 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.degree.-420.degree. 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.
