  2. Shilov system - Wikipedia

    en.wikipedia.org/wiki/Shilov_system

    Shilov cycle The overall charge is omitted from the complexes since the exact coordination sphere of the active species is unknown. The Shilov system is a classic example of catalytic C-H bond activation and oxidation which preferentially activates stronger C-H bonds over weaker C-H bonds for an overall partial oxidation.

  3. Partial oxidation - Wikipedia

    en.wikipedia.org/wiki/Partial_oxidation

    Partial oxidation (POX) is a type of chemical reaction. It occurs when a substoichiometric fuel-air mixture is partially combusted in a reformer, creating a hydrogen-rich syngas which can then be put to further use, for example in a fuel cell. A distinction is made between thermal partial oxidation (TPOX) and catalytic partial oxidation (CPOX).

  4. Catalytic oxidation - Wikipedia

    en.wikipedia.org/wiki/Catalytic_oxidation

    Most methane is stranded, i.e. not located near metropolitan areas. Consequently, it is flared (converted to carbon dioxide). One challenge is that methanol is more easily oxidized than is methane. [3] Catalytic oxidation with oxygen or air is a major application of green chemistry. There are however many oxidations that cannot be achieved so ...

  5. Methane monooxygenase - Wikipedia

    en.wikipedia.org/wiki/Methane_monooxygenase

    Methane monooxygenase belongs to the class of oxidoreductase enzymes (EC 1.14.13.25). There are two forms of MMO: the well-studied soluble form (sMMO) and the particulate form (pMMO). [2] The active site in sMMO contains a di-iron center bridged by an oxygen atom (Fe-O-Fe), whereas the active site in pMMO utilizes copper.

  6. Methane reformer - Wikipedia

    en.wikipedia.org/wiki/Methane_reformer

    A methane reformer is a device based on steam reforming, autothermal reforming or partial oxidation and is a type of chemical synthesis which can produce pure hydrogen gas from methane using a catalyst. There are multiple types of reformers in development but the most common in industry are autothermal reforming (ATR) and steam methane ...

    en.wikipedia.org/wiki/Sabatier_reaction

    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.

    en.wikipedia.org/wiki/Heterogeneous_catalysis

    In automobiles, catalytic converters are used to catalyze three main reactions: The oxidation of carbon monoxide to carbon dioxide: 2CO(g) + O 2 (g) → 2CO 2 (g) The reduction of nitrogen monoxide back to nitrogen: 2NO(g) + 2CO(g) → N 2 (g) + 2CO 2 (g) The oxidation of hydrocarbons to water and carbon dioxide: 2 C 6 H 6 + 15 O 2 → 12 CO 2 ...

  9. Anaerobic oxidation of methane - Wikipedia

    en.wikipedia.org/wiki/Anaerobic_oxidation_of_methane

    Three mechanisms of Anaerobic Oxidation of Methane (AOM). The first method (top) is mediated by a consortium of anaerobic methanotrophic (ANME) archaea from the clades 1,2a,2b & 2c and sulfate reducing bacteria (SRB). The oxidation of methane occurs in the ANME where electrons are passed directly to the SRB, which performs sulfate reduction [3 ...
