Abstract: The article presents data on the study of the possibility of obtaining pitch from coal by thermal dissolution in a mixture of anthracene fraction and heavy fraction of the liquid pyrolysis product of rubber products. According to this method, with a mass ratio of coal to solvent - 40/60% by weight. at a temperature in the reactor - 400 oC, as well as at a ratio of the anthracene fraction to the heavy fraction of the liquid pyrolysis product of rubber products 50/50% by weight. It is possible to obtain a baking-like product. This method makes it possible to reduce the cost of the anthracene fraction in obtaining peak-like products by using a heavy fraction of the liquid pyrolysis product of rubber products as its partial replacement. The coal of the Kuznetsk basin is used as a raw material for thermal dissolution. Experimental data have proved the production of coal peak-like products, which can be a potential raw material for the production of binders for electrode masses and briquetting of solid hydrocarbon fuels and raw materials for the production of carbon fibers. Such a baking product is characterized by the lowest ash content and can be used as a sintering additive to the coking charge (obtaining high-quality coke, the use of ramming the charge or other methods of caulking the charge).
