Why do they call coal coke?

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. The unqualified term “coke” usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking.

What is difference between coke and coal?

Coal is a lustrous, black fossil fuel that includes impurities, generates smoke, and generates less heat than coke when burned. Coke is a dingy, black coal waste that burns hotter and cleaner. Coke is a fuel made from mineral coal that has been calcined or dry distilled.

Are both coke and coal different forms of same element?

Coal contains a lot of impurities however coke is obtained as a residue and is far more refined. Impurities like carbureted hydrogen, naptha and ammonia are removed from coal in the gaseous form and therefore coke is mainly a pure form of carbon.

Coke has a high carbon content and low ash and sulphur content which makes it very highly priced in the market.

Which is the best definition of a semicoke?

Definition of semicoke. : the solid residue obtained by carbonization especially of coal at a relatively low temperature (as below 700° C) that is in general softer and more friable than coke from carbonization at higher temperatures, that gives a hot smokeless fire, and that can be used as a domestic fuel.
