Coke (fuel) - Wikipedia

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. 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 concern.. The unqualified term "coke" usually refers to the product derived from low ...

Sep 06, 2019 · Coal contains less energy for the amount of carbon it contains than oil or gas. As a result, burning coal releases more carbon dioxide than burning either oil or gas (for the same energy). And yet coal is the most common fossil fuel and so we continue to burn large amounts of it. Coal is the biggest contributor to global warming.

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 if dead plant matter decays into peat and over millions of years the heat and pressure of deep burial converts the peat into coal.

What Is the Environmental Impact of Mining and Burning Coal?

Coal starts as peat, or sections of partially decomposed organic matter that accumulate on the earth's surface. Over millions of years, the peat is buried and heat and pressure transform it into increasingly pure forms of coal called lignite, sub-bituminous, bituminous, and anthracite coal.. These fossil fuels are limited or nonrenewable resources; after they serve their fuel purpose, they ...
