Abstract: The article considers the possibility of obtaining baking-like products from coal by thermal dissolution. The production of pitch-like products from coal will reduce the shortage in the Russian and world markets of coal pitch, which is widely used as a raw material for electrode production, production of carbon fibers, etc. The most suitable raw materials for the production of baking-like products by thermal dissolution are coal grade GZH. The analysis of the reserves of these coals in Kuzbass was carried out, enterprises producing GJ brand coals were identified, the qualitative characteristics of these coals were investigated. Studies have been conducted to obtain baking-like products by thermal dissolution of GJ brand coals in an organic solvent. The anthracene fraction of coal tar (anthracene oil) was used as a solvent of coal coals. Experimental studies on the thermal dissolution of coals were carried out when the final temperature of the process varied from 370 to 390 ° C. The ratio of anthracene oil and coal in the reaction mixture was 70/30 and 60/40. Qualitative characteristics were determined for the obtained laboratory samples of baking-like products. The analysis of the obtained experimental results is carried out, conclusions are drawn about the influence of temperature and composition of coal oil paste on the quality of the obtained baking-like products of thermal dissolution of coals.
