The results of investigation of the effect of mechanochemical treatment of coal under the shock-shear action on coal liquefaction process in a hydrogen-donor solvent are presented. In order to explain the choice of coal raw material most easily subjected to mechanical activation and thermal dissolution, the investigation was carried out with vitrinite concentrates of brown and black coal samples with different degree of metamorphism of technological grades D, G, Zh, K (R₀ = 0.4-1.25 %). It was shown that liquefaction of mechanochemically activated coal not only results in an increase in the yield of liquid products of the transformation of the organic matter of coal samples but also in substantial changes in their qualitative composition.
