What You Should Know About Metallurgical Coal ThoughtCo

Terence Bell. Updated on August 21, 2020. Metallurgical coal, also known as coking coal, is used to produce coke, the primary source of carbon used in steelmaking. Coal is a naturally occurring sedimentary rock formed over millions of years as plants and other organic materials are buried and subjected to geological forces.

What is coking coal, and where is it used? | Kalkine Media

Metallurgical or coking coal is a primary ingredient in the steel making process. More than twothirds of global steel is produced in basic oxygen blast furnaces. China is the largest consumer of premium coking coal in the world. Coking coal, generally known as metallurgical coal, is a naturally occurring sedimentary rock.

Metallurgical coals fall broadly into two types (Figure 1). Coking coal is heated in the absence of oxygen in a coke oven to produce coke, which is then charged into blast furnaces as the key fuel and reactant. Coking coal can be further divided into hard coking coal (HCC), semihard coking coal (SHCC) and semisoft coking coal (SSCC).

It can be seen from Figure 3 that under the same pressure condition, with the increase in temperature, the gas adsorption capacity of coking coal shows a downward trend. This is because the adsorption of coal to gas belongs to physical adsorption, and adsorption is an exothermic process (Wang et al., 2012).So, with the rise in temperature, the gas molecules move more violently, and the time ...
