Coke (fuel) Raw coke. Coke is a grey, hard, and porous coalbased 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 ...
Properties of Coal • Coal properties are evaluated by different methods. • The most commonly used methods are Proximate and Ultimate analysis of the coal. • Proximate analysis gives the Moisture, Ash and Volatile matter, while the Fixed Carbon is found by difference. • Ultimate Analysis gives the elemental composition of the coal.
Other articles where carbonization is discussed: chemical industry: Benzene: was obtained from the carbonization (heating) of coal, which produces coke, combustible gas, and a number of byproducts, including benzene. Carbonization of coal to produce illuminating gas dates back in England to the very early years of the 19th century. The process is still employed in some countries, but.
Formation • The transformation of the vegetable debris to coal takes place in two stages: (a) Biochemical or peat stage: During this stage, the plant materials were attacked by various micro organisms. (b) Chemical stage or metamorphism: In this stage, the peat deposit buried under sedimentary deposits lose moisture and volatile components under the effect of high temperature and ...
