Differentiation of coking & non-coking coals: From physical appearance it is very difficult if not impossible to differentiate between non-coking & a coking coal. A non – caking coal is that coal which when heated in the absence of air for e.g. as in the determination of VM, leaves a powdery residue. A non-caking coal is always a non-coking coal.

Coking coal, or metallurgical coal, has been produced in the United States for nearly 200 years. Coking coal is primarily used in the production of coke for use in the steel industry, and for other uses (for example, foundries, blacksmithing, heating buildings, and brewing). Currently, U.S. coking coal is produced in Alabama, Arkansas, Pennsylvania, ia , and West ia.

Coking is the heating of coal in the absence of oxygen to a temperature above 600 °C to drive off the volatile components of the raw coal, leaving a hard, strong, porous material of high carbon content called coke.Coke consists almost entirely of hydrocarbons.The porosity gives it a high surface area, which makes it burn faster (as does a sheet of paper versus a wooden log).
