What Is the Difference Between Coal and Coke Fuel?

Coke is a byproduct of bituminous coal. When coal undergoes a process known as destructive distillation, it converts to coke. This process entails heating the fuel at a high temperature with no oxygen. The impurities and flammables burn off when coal changes to coke, and the result is a dull, porous substance with high carbon content. Although ...

12.2 Coke Production

12.2 Coke Production 12.2.1 General Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygen-free atmosphere (–coked–) until most volatile components in the coal are removed. The material remaining is a carbon mass called coke.

Coke (fuel)

Coking is a refinery process that produces 19% of finished ...

 · Coking is a refinery unit operation that upgrades material called bottoms from the atmospheric or vacuum distillation column into higher-value products and, as the name implies, produces petroleum coke—a coal-like material. Exports of petroleum coke accounted for about 19% of the nation''s finished petroleum product exports through October 2012 with most going to China and other Asian …

Metallurgical Coke

Processing. Metallurgical coal is used in the production and purification of metcoke. It is during the heating process that the unstable components are released. The final product is a non-melting, solid, stable carbon. However, the "ash" elements, which were part of the original bituminous coal, remain encapsulated in the resultant metcoke.

Coke Making Process

Coke is produced by igniting bituminous coal under reduced oxygen conditions in oven batteries specially designed for this process. The coking process generates the following main volatiles as byproducts: coke oven gas, tar, ammonium sulfate, benzol, toluol and naphtha.

The Process of Coke Production

Coke is manufactured by burning coal under optimal oxygen settings in kiln batteries, particularly for this production process. The coke manufacturing procedure results in various byproducts, including ammonium sulfate, naphtha, ammonium sulfate, coke oven gas, and tar.

AP 42 12.2 Coke Production

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".

What is Coking Coal

Coke is produced by heating coking coals in a coke oven in a reducing atmosphere. As the temperature of the coal increases, it becomes plastic, fusing together before resolidifying into coke particles. This is known as the caking process.
