Abstract
The article discusses the process of thermal dissolution of the organic mass of coal in anthracene oil in order to obtain baking-like products. Baking products are valuable raw materials for the production of carbon fibers and in the production of electrodes. Earlier studies on the thermal dissolution of coal in anthracene oil have shown that the most suitable raw materials for this process are coal grades G, GJ and Zh. The analysis of the coal base of the Kemerovo region – Kuzbass was carried out in order to select the sources of raw materials for the technology of obtaining pitches. The analysis showed that in Kuzbass today there are 28 enterprises (mines and sections) that extract coals of the G, GJ and Zh grades. The most suitable sources of coals of these brands are those that have a low ash content, the reflectivity of vitrinite up to 1% and the maximum possible thickness of the plastic layer of coal.
