  2. Coal gasification - Wikipedia

    en.wikipedia.org/wiki/Coal_gasification

    In industrial chemistry, coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), methane (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".

  3. Coal - Wikipedia

    en.wikipedia.org/wiki/Coal

    Water systems are affected by coal mining. [145] For example, the mining of coal affects groundwater and water table levels and acidity. Spills of fly ash, such as the Kingston Fossil Plant coal fly ash slurry spill, can also contaminate land and waterways, and destroy homes. Power stations that burn coal also consume large quantities of water.

  4. Coke (fuel) - Wikipedia

    en.wikipedia.org/wiki/Coke_(fuel)

    The coal is baked in an airless kiln, a "coke furnace" or "coking oven", at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F). [2] This process vaporises or decomposes organic substances in the coal, driving off water and other volatile and liquid products such as coal gas and coal tar. Coke ...

  5. Fischer–Tropsch process - Wikipedia

    en.wikipedia.org/wiki/Fischer–Tropsch_process

    Synthesis gas ("syngas") is obtained from biomass/coal gasification is a mixture of hydrogen and carbon monoxide. The H 2:CO ratio is adjusted using the water-gas shift reaction. Coal-based FT plants produce varying amounts of CO 2, depending upon the energy source of the gasification process. However, most coal-based plants rely on the feed ...

  6. Geology of the Appalachians - Wikipedia

    en.wikipedia.org/wiki/Geology_of_the_Appalachians

    The Appalachian Basin is one of the most important coal producing regions in the U.S. and one of the largest in the world. Bituminous coal has been mined throughout the last three centuries. Currently, the coal primarily is used within the eastern U.S. or exported for electrical power generation, but some of it is suitable for metallurgical ...

  7. Water gas - Wikipedia

    en.wikipedia.org/wiki/Water_gas

    The process used the water-gas shift reaction: CO + H 2 O → CO 2 + H 2. The process was discovered by passing high-pressure steam over hot coal, the major source of coke gas. Lowe's process improved upon the chimney systems by which the coal could remain superheated, thereby maintaining a consistently high supply of the gas.

  8. Gething Formation - Wikipedia

    en.wikipedia.org/wiki/Gething_Formation

    The Gething Formation contains coal seams that range from thin laminae to as much as 4.3 meters (14 ft) thick. Coal rank ranges from low- to high-volatile bituminous, and the coal has good coking properties except where oxidized. [4] It has been mined by underground methods near the Peace River west of Hudson's Hope and near the Sukunka River.

  9. Carbon cycle - Wikipedia

    en.wikipedia.org/wiki/Carbon_cycle

    The movement of terrestrial carbon in the water cycle is shown in the diagram on the right and explained below: [38] Atmospheric particles act as cloud condensation nuclei, promoting cloud formation. [39] [40] Raindrops absorb organic and inorganic carbon through particle scavenging and adsorption of organic vapors while falling toward Earth ...
