Gusak V. Development of scientific principles and practice of obtaining high-quality coke from coals of different basins

The thesis is devoted to theoretical and experimental research on the production of low-reactive high durable metallurgical coke under interbasin resource base of coking enterprises of Metinvest LTD. The experimental data allowed formulating metallurgical coke quality requirements set out in the "TУУ 19.1-00190443-065:2012 " Metallurgical coke. Pilot batch" The comparative study of Ukrainian and American coals of equal metamorphism degree has been conducted, differences in the structure and technological properties have been revealed. It is found that the organic mass of American coal at all stages of metamorphic changes in the range vitrinite reflectance of 0.7 to 1.8 % contained more carbon and had a greater degree of unsaturation by hydrogen of the organic structure of coal mass compared to Ukrainian coals with equal metamorphism degree. It is proved that the US coals with vitrinite reflectance index up 1 % relate to reduced coals and Ukrainian coal of the same metamorphism degree apply to low reduced coals. With increasing degree of metamorphism (R> 1) US coals are low reduced coals and Ukrainian coals are reduced coals.
