摘要： 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.

摘要： 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.
