Upgrading coke quality of coals by adding a pitch-like product with a softening point (K-S) of 90 DEG -160 DEG 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. |
