Describe how coal was formed. What is this process called

The slow process by which the dead plants buried under the Earth have become coal is called as carbonisation. Since coal was formed from the remains of the plants, it is called a fossil fuel. Coal, which is mainly carbon, on heating produces mainly carbon dioxide gas and a

1998-6-25  In the jargon of the coal business, this procedure is called the ultimate analysis of coal. Carbon and hydrogen are the principal combustible elements in coal. On a weight basis, carbon is the predominant one. It constitutes about 60% to about 95% of the total. For most coals of 90% or less carbon, hydrogen content is generally in

What is Coke - Clean Air Council – Clean Air Council

Coke is produced by heating coal at high temperatures, for long periods of time. This heating is called “thermal distillation” or “pyrolysis.” In order to produce coke that will be used in blast furnaces, coal is usually thermally distilled for 15 to 18 hours, but the process can take up to 36 hours.
