Differentiation of coking & non-coking coals

caking coal might give a coke which may not be accepted by the steel plants as it does not possess the requisite physical and chemical properties of the coke. A coking coal is that coal which on heating in absence of air leaves a solid residue. A non-coking coal also leaves a solid coherent residue which may not possess the physical & chemical properties of the coke. The non-coking coals are ...

Coal - Wikipedia

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.

How coal is converted into coke? | AnswersDrive

Coke making. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The physical properties of coking coal cause the coal to soften, liquefy and then resolidify into hard but porous lumps when heated in the absence of air.
