The reactivities of brown coals of six deposits of the Kansk-Achinsk basin in hydrogenation under a pressure of 10 MPa have been studied and an influence of the properties of the coal on the depth of conversion and on the yield and composition of the gaseous products has been shown. It has been established that the reactivities of coals in hydrogenation depends on the petrographic composition and the nature of bonds of the oxygen in the organic substances of the coals with a decrease in the amount of fusinite and an increase in the amount of oxygen of cyclic structures and also in the so-called ''bridge'' bonds the depth of conversion of the coal into liquid products rises. A correlation is observed between the capacity of coals for reacting with phenol in the presence of p-toluenesulfonic acid and the yield of liquid products in their hydrogenation, which indirectly shows a considerable role of alkyl bridge bonds of the coals substances in hydrogenation. The majority of the coals of the Kansk-Achinsk basin is a favorable raw material for hydrogenation, with the exception of the samples of the Barandat deposit that were studied, which are rich in microcomponents of the fusinite group.
