Refined coal is the product of a coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals. It is one form of several precombustion treatments and processes for coal that alter coal's characteristics before it is burned.

Drawing the retorts at the Great Gas Establishment Brick Lane, from The Monthly Magazine (1821). The history of gaseous fuel, important for lighting, heating, and cooking purposes throughout most of the 19th century and the first half of the 20th century, began with the development of analytical and pneumatic chemistry in the 18th century.
The science of thermodynamics was developed into its modern form by Sadi Carnot, William Rankine, Rudolf Clausius, William Thomson, James Clerk Maxwell, Ludwig Boltzmann and J. Willard Gibbs. These scientific principles were applied to a variety of industrial concerns, including improving the efficiency of boilers and steam turbines.
Coal forms when organic matter builds up in waterlogged, anoxic swamps, known as peat mires, and is then buried, compressing the peat into coal. The majority of Earth's coal deposits were formed during the late Carboniferous and early Permian. The plants from which they formed contributed to changes in the Carboniferous Earth's atmosphere.
