摘要：

The results of the hydrogenation processing of coal from the Shubarkol deposit in the presence of natural bauxites from the Turgai deposit in the Republic of Kazakhstan are reported. With the use of a sample of bauxite containing 23.7% Fe2O3 as a catalyst, a higher yield of liquid products (54.2%) was obtained, as compared with those on other bauxite samples (49.5-53.8%). It was established that the modification of catalysts containing iron with elemental sulfur additives (0.75-1.25%) makes it possible to increase the yield of liquid products to 62.3-67.3%. A positive role of the preliminary ozonization of coal, which makes it possible to increase the yield of total liquid products upon hydrogenation by 13.3% in comparison with the yield of liquid products obtained with the use of coal not treated with ozone, was demonstrated.
