Raw coke. Coke is a grey, hard, and porous coal-based fuel with a high carbon content. It is made by heating coal or oil in the absence of air. Coke is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges. The unqualified term "coke" usually refers to the product derived from low-ash and low ...
Metallurgical coal or coking coal[1] is a grade of coal that can be used to produce good-quality coke. Coke is an essential fuel and reactant in the blast furnace process for primary steelmaking. [2][3][4] The demand for metallurgical coal is highly coupled to the demand for steel. Primary steelmaking companies often have a division that ...
Coking is the heating of coal in the absence of oxygen to a temperature above 600 °C (1,112 °F) to drive off the volatile components of the raw coal, leaving a hard, strong, porous material of high carbon content called coke. Coke is almost all carbon. The porosity gives it a high surface area, which makes it burn faster (as does a sheet of ...
The Pittsburgh coal seam is the thickest and most extensive coal bed in the Appalachian Basin; [1] hence, it is the most economically important coal bed in the eastern United States. The Upper Pennsylvanian Pittsburgh coal bed of the Monongahela Group is extensive and continuous, extending over 11,000 mi 2 through 53 counties.

Town gas is a more general term referring to manufactured gaseous fuels produced for sale to consumers and municipalities. [1]
Petcoke is the coke that, in particular, derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units termed coker units. [1] (. Other types of coke are derived from coal.) Stated succinctly, coke is the " carbonization ...
The Connellsville Coalfield is located in Fayette County and Westmoreland County, Pennsylvania, between the city of Latrobe and the small borough of Smithfield. It is sometimes known as the Connellsville Coke Field. This is because the section of the Pittsburgh coal seam here was famous as one of the finest metallurgical coals in the world.
Anthracite coal, coke, bituminous coal dust and waste, lignite, or biomass. Manufactured by the incomplete combustion of varying carboniferous feedstocks in an extremely hot (>= 1100 °C), limited-oxygen atmosphere aided by the injection of a small, stoichiometric flow of steam.
