Jun 1, 2022The utilization of high sulfur coking coals in metallurgical coke industries is necessary and critical to protect the high-quality coal resources and reduce the cost of coal blending [1]. The production of high organic-sulfur coking coal (HOSC) has accounted for an increasing proportion of the total production of coking coals in China.

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
