Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coal Carbonization for Coke Production – IspatGuru

Dec 08, 2018· Coal Carbonization for Coke Production.

Coal formation is a very controversial issue in the creation vs. evolution argument, and one that has been under debate for many years. Secular (or uniformitarian) geologists traditionally teach that coal is formed at the bottom of swamps over millions of years of uniform peat deposition.

Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbon-based material - approximately 50% of its weight. The formation of coal takes a significant amount of time (on the order of a few million years), and the first coal-bearing rock units appeared about 290-360 million years ago, at a time known as the Carboniferous or "coal-bearing" Period.
