    Paul Sabatier (1854-1941) winner of the Nobel Prize in Chemistry in 1912 and discoverer of the reaction in 1897. The Sabatier reaction or Sabatier process produces methane and water from a reaction of hydrogen with carbon dioxide at elevated temperatures (optimally 300–400 °C) and pressures (perhaps 3 MPa [1]) in the presence of a nickel catalyst.

    With concentrations of atmospheric methane increasing twice as fast as carbon dioxide since 1750, methane is the second most impactful greenhouse gas. [2] [3] Worldwide methane emissions from agriculture in 2019. Atmospheric methane has increased since pre-industrial times from 0.7 ppm to 1.9 ppm. [4]

  6. 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".

  7. Carbon-neutral fuel - Wikipedia

    en.wikipedia.org/wiki/Carbon-neutral_fuel

    The carbon dioxide used to make synthetic fuels may be directly captured from the air, recycled from power plant flue exhaust gas or derived from carbonic acid in seawater. Common examples of synthetic fuels include ammonia and methane , [ 2 ] although more complex hydrocarbons such as gasoline and jet fuel [ 3 ] have also been successfully ...
