Abstract

The article considers the possibility of obtaining peak-like products from hard coals by thermal dissolution of the organic mass of coals in organic solvents. The relevance of this topic is related to the shortage in the Russian and world markets of coal pitch used as raw materials for the production of carbon materials and in the production of electrodes. Studies have been conducted on the thermal dissolution of coals of grades G, GJ, W in anthracene oil. During the experiment, the following parameters were changed: the brand of coal, the ratio of coal: solvent, the temperature of the process. For the resulting baking-like product, the following quality parameters were determined: softening temperature, product yield, fractional composition.

Keywords

Coal, Anthracene oil, Pitch-like product, Pitch, Thermal dissolution, Softening temperature.
