Coal gas is a flammable gaseous fuel made from coal and supplied to the user via a piped distribution system. It is produced when coal is heated strongly in the absence of air.

coal gas, gaseous mixture—mainly hydrogen, methane, and carbon monoxide—formed by the destructive distillation (i.e., heating in the absence of air) of bituminous coal and used as a fuel.

In industrial chemistry, coal gasification is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4), and water vapour (H2O)—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".

Coal gas, also known as a gaseous mixture, is a fuel made up of hydrogen, methane, and carbon monoxide produced by destructive distillation (continuous heating in the absence of air) of bituminous coal.

2025年3月27日 · Coal, one of the most important primary fossil fuels, a solid carbon-rich material, usually brown or black, that most often occurs in stratified sedimentary deposits, which may later be subjected to high temperatures and pressures during mountain building, resulting in the development of anthracite and even graphite.

4 天之前 · What was once Pennsylvania’s biggest coal-fired power plant is being turned into a $10 billion natural gas-powered data center campus designed to capitalize on Big Tech's fast-growing energy demands.

2024年4月17日 · Coal is an abundant fuel source that is relatively inexpensive to produce and convert to useful energy. However, producing and using coal affects the environment.

Coal gas is a gaseous mixture, mainly composed of methane, hydrogen, and carbon monoxide that are formed by the destructive distillation (it means heating in the absence of air) of bituminous coal and is also used as a fuel.

Compare coal vs natural gas in terms of efficiency, cost, environmental impact, and U.S. use of each fuel for electricity generation through history.

Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. [1] Coal is a type of fossil fuel, formed when dead plant matter decays into peat which is converted into coal by the heat and pressure of deep burial over millions of years. [2]
