Methanation is the conversion of carbon monoxide and carbon dioxide (CO x) to methane (CH 4) through hydrogenation. The methanation reactions of CO x were first discovered by Sabatier and Senderens in 1902. [1] CO x methanation has many practical applications.
Biological methanation in a pressurized reactor vessel (in-situ process). Pressure allows for better hydrogen solubility and therefore easier conversion into methane by microorganisms. [10] A possible reactor configuration can be Autogenerative high-pressure digestion. Research in Korea has demonstrated that 90% > CH4, 180 MJ/m3 biogas can be ...
Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...
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.
The oxidative coupling of methane (OCM) is a potential chemical reaction studied in the 1980s for the direct conversion of natural gas, primarily consisting of methane, into value-added chemicals. Although the reaction would have strong economics if practicable, no effective catalysts are known, and thermodynamic arguments suggest none can exist.
The mechanism for the conversion of CH 3 –S bond into methane involves a ternary complex of the enzyme, with the substituents forming a structure α 2 β 2 γ 2 . Within the complex, methyl coenzyme M and coenzyme B fit into a channel terminated by the axial site on nickel of the cofactor F430 . [ 6 ]
Methane-rich gases are converted into liquid synthetic fuels. Two general strategies exist: (i) direct partial combustion of methane to methanol and (ii) Fischer–Tropsch-like processes that convert carbon monoxide and hydrogen into hydrocarbons. Strategy ii is followed by diverse methods to convert the hydrogen-carbon monoxide mixtures to ...
