Fig 1 Types of coal and their uses. The term ‘coking coal’ is used to designate certain types of bituminous coals which, when heated at high temperatures (over 1, deg C) in the absence of air (carbonization), soften, liquefy, and then re-solidify into a hard but porous mass known as coke, used mainly in the production of hot metal in a blast furnace.

The U.S. Department of Energy's Office of Scientific and Technical Information. Coke, solid residue remaining after certain types of bituminous coals are heated to a high temperature out of contact with air until substantially all of the volatile constituents have been driven off. The residue is chiefly carbon, with minor amounts of hydrogen, nitrogen, sulfur, and oxygen.

To predict the coke stability of a high or medium volatile coal sample the effective content index calculated from petrographic data is plotted with the “normal” vitrinite reflectance.
Note the pronounced peak in the curves, indicating an optimum inert content, and that the strength increases with rank.
Coking coals. Although chemical composition alone cannot be used to predict whether a coal is suitable for coking, prime coking coals generally have volatile matter contents of 20 to 32 percent—i.e., the low- and medium-volatile bituminous ranks.
When heated in the absence of air, these coals first become plastic, then undergo decomposition, and finally form coke when the decomposed material. Various blends of Illinois high volatile bituminous coals and different percentages of medium and low volatile bituminous coals from the Appalachian fields were coked.
In three series, Illinois and medium volatile coals were coked independently and then in blends consisting of 20 percent variations of the proportion of the two coals. Purchase Coke - 2nd Edition.

including the fines, for making coke. Utilization of all, or a very large percentage of, mine output for coke should have economic advantages for both coal and coke producers.

Herbert Richter, André Werner, in Low-Rank Coals for Power Generation, Fuel and Chemical Production, Introduction. Coal pyrolysis has been considered an attractive means of using coal, especially for low rank coal/lignite and with the beginning of the worldwide oil crisis of the s, researchers started again significant effort on studying coal pyrolysis due to the importance.
Illinois No. 6 coal blended wlth medium-volatile Virginia coal also pro- duced strong coke and exerted uniformly low expansion pressures, only a little higher than those of the previous series. Here, however, a small increase in peak pressure was noted at the 24h-hour coking rate.

Coke is a cleaner, and it gets hotter burning fuel than coal, but it also requires more air to light and remain lit. Make sure that your fire pot can handle the extra heat when using coke.
