The benification process of low-methamorphized coal was investigated. As a result the coal ash content reduces to 3.2-5.6 wt%. Using X-ray analysis the effect of coal inorganic matter on the beneficiation and desulphurization of coal was studied. The effect of oxidant linear rate (OLR) and coal grain size on the yield and quality of main products was examined. When OLR is more than 0.044-0.066 m/s the increase in grain size to 0.5 mm practically does not affect coal desulphurization.5481 Product Description popup.authors Астахова Олена Тарасівна Братичак Михайло Миколайович Гунька Володимир Мирославович Пиш'єв Сергій Вікторович Присяжний Юрій Володимирович popup.nrat_date 2020-04-02 Close
