Abstract
The article presents the data of physico-chemical studies of the coals of the Kuzbass basin used for the technology of obtaining pitch and pitch-like products from coal by the method of thermal dissolution of the organic mass of coals in organic solvents. The relevance of these studies is related to the shortage in the Russian and world markets of coal pitch. Studies were carried out on the technical analysis of coals, plastometric indicators were determined, the index of swelling in the crucible was determined, data on the petrographic analysis of coals were obtained.
Keywords
Coal, Pitch-like product, Pitch, Thermal dissolution, Temperature physico-chemical studies.
