Metallurgical Coke - an overview | ScienceDirect Topics

Metallurgical coke is an important raw material for pig iron production in the blast furnace. During this process the coke undergoes severe mechanical, thermal and chemical stresses. One of these is the CO 2-gasification which may lead to a decisive mechanical weakening of the lump coke by increased carbon burn-off. The CO 2-reactivity is influenced by different parameters as e.g. temperature ...

Coke (fuel) - Wikipedia

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern. The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. A similar product called petroleum coke, or pet coke, is obtained from crude oil in oil …

Coal - Wikipedia

Coke is a solid carbonaceous residue derived from coking coal (a low-ash, low-sulfur bituminous coal, also known as metallurgical coal), which is used in manufacturing steel and other iron products. Coke is made from coking coal by baking in an oven without oxygen at temperatures as high as 1,000 °C, driving off the volatile constituents and fusing together the fixed carbon and residual ash.

Metallurgical Coal

Metallurgical coal is more scarce and valuable than thermal coal, so in practice metallurgical coal is rarely used to generate electricity. Metallurgical coal is also common-ly referred to as coking coal. Coking coal has physical properties that when heated cause it to soften, liquefy and then resolidify into a harder substance known as coke.
