  2. Coal gas - Wikipedia

    en.wikipedia.org/wiki/Coal_gas

    By-products from the production process included coal tars and ammonia, which were important raw materials (or "chemical feedstock") for the dye and chemical industry with a wide range of artificial dyes being made from coal gas and coal tar. Facilities where the gas was produced were often known as a manufactured gas plant (MGP) or a gasworks.

  3. Coal gasification - Wikipedia

    en.wikipedia.org/wiki/Coal_gasification

    If, however, hydrogen is the desired end-product, the coal gas (primarily the CO product) undergoes the water gas shift reaction where more hydrogen is produced by additional reaction with water vapor: CO + H 2 O → CO 2 + H 2. Although other technologies for coal gasification currently exist, all employ, in general, the same chemical processes.

    Generally mixed with coal gas, valued for being able to be produced "just in time" with 1 hour's notice, unlike coal gas, which would require 4+ days to bring online from idle. Low labor and capital costs, however, high, inefficient use of anthracite/coke feedstock. Carburetted water gas: Water gas and petroleum or coal tar.

  5. History of coal mining - Wikipedia

    en.wikipedia.org/wiki/History_of_coal_mining

    The History of coal mining goes back thousands of years, with early mines documented in ancient China, the Roman Empire and other early historical economies. It became important in the Industrial Revolution of the 19th and 20th centuries, when it was primarily used to power steam engines, heat buildings and generate electricity.

    Carbon capture and storage (CCS) can be used to capture carbon dioxide from the flue gas of coal power plants and bury it securely in an underground reservoir. Between 1972 and 2017, plans were made to add CCS to enough coal and gas power plants to sequester 161 million tonnes of CO 2 per year, but by 2021 98% of these plans had failed. [169]

    The surge of natural gas production in the U.S. has opened several doors that many didn't think were previously economically feasible: Manufacturers are reconsidering a move back to the U.S. for ...

  8. Underground coal gasification - Wikipedia

    en.wikipedia.org/wiki/Underground_coal_gasification

    Underground coal gasification converts coal to gas while still in the coal seam (in-situ). Gas is produced and extracted through wells drilled into the unmined coal seam. Injection wells are used to supply the oxidants (air, oxygen) and steam to ignite and fuel the underground combustion process. Separate production wells are used to bring the ...
