Coke is a solid carbonaceous residue derived from low-ash, low-sulfur bituminous coal from which the volatile constituents are driven off by baking in an oven without oxygen at temperatures as high as 1,000 °C (1,832 °F) so that the fixed carbon and residual ash are fused together.

Why coke is better than coal?
Coke is better than coal for certain industrial processes and applications because it is a purer form of carbon with higher heat output and lower impurities. This makes coke more efficient and cleaner burning than coal, making it preferable for use in iron and steel production.
What is the burning point of coal?
The burning point of coal depends on the type of coal, but it generally ranges from 700°C to 1300°C. At these temperatures, coal combusts and releases heat energy.
Why is coke preferred over coal for burning?
Coke, often made from bituminous coal refuse, is formed from burning off volatile components. That leaves solid fuel that burns longer and hotter than coal.Anthracite (hard) coal burns the hottest and cleanest, but this coal is in shorter supply because it takes longest to form.Bituminous (soft) coal has variable amounts of volatile components (low, medium, high) and burns 'dirty'. But it provides long, fairly even burning.Factories could and did use bituminous coal. But burning coal refuse to make coal rescued the coal while getting rid of gunk and impurities. Steel mills, which needed high, even, and longer-lasting burns for steel production, required coke.For coal companies, mining and processing of "coal and coke" increased revenues from all grades of coal. At one point, Fayette County and Washington County both in SW Pennsylvania were dotted with "beehive" coke ovens used to burn off coal's impurities.
What are advantages of coke over coal?
coke burns without producing smoke and leaves no residue... also its calorific value (or the amount of heat it produces) is higher than coal... Coke is the purest form of carbon . It is used in the manufacturing of steel and in the extraction of many metals . coke has least amount of carbon arond 27%
Does coke contain coal?
The name "Coke" is derived from the original ingredient used in the soda's flavoring, which was a combination of the coca plant and the kola nut. There is no coal in Coca-Cola.

What raw materials are used to make coke?
A coal and heat process that removes sulphur and other impurities without actually burning the coal.

What do coal coke peat and paraffin have in common?
Coal, Coke, Peat and Paraffin are all fuels.

What is the difference between pet-coke and coal-coke?
Pet-coke, or petroleum coke, is a byproduct of the oil refining process, while coal-coke is a byproduct of coal carbonization. Pet-coke has a higher carbon content and lower impurities compared to coal-coke, making it a more efficient fuel source. Pet-coke is typically used in industrial processes, while coal-coke is mainly used in the steel industry.

How is it produced coke from coal?
Coke is produced from coal through a process called destructive distillation. In this process, coal is heated in the absence of air to drive off volatile components, leaving behind coke. The coke produced is a porous material that is used as a fuel and as a reducing agent in the smelting of iron ore.
What type of coal is used to make coke?
Metallurgical coal, also known as coking coal, is used to make coke. This type of coal has high carbon content and low impurities, making it suitable for the production of coke, which is used in the steelmaking process.
