THE MATERIAL COMPOSITION AND REACTIVITY OF VITRINITES OF HARD COALS OF VARIOUS DEGREES OF REDUCTION

摘要

The authors consider the trends in the investigation of the material composition and structure of vitrinites of hard coals of various degrees of reduction. The relationship has been analyzed between the specific structure and material composition of coals of Donetsk and Kuznetsk basins of various degrees of reduction and their reactivity in processes of coke formation upon joint pyrolysis with organic additions, thermal preparation and also upon combustion of water-coal suspensions.
