Аннотация: the article summarizes the results of the research. The influence of cavitation-wave action on coal tar, which leads to a change in the rheological properties (density, viscosity), as a result of an increase in the yield of light and medium fractions, is investigated, and the process of catalytic hydrogenation of coal in the presence of a catalytic additive and mine methane is studied.
