  2. Sabatier reaction - Wikipedia

    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.

  3. Heterogeneous catalysis - Wikipedia

    en.wikipedia.org/wiki/Heterogeneous_catalysis

    Zeolite structure. A common catalyst support material in hydrocracking. Also acts as a catalyst in hydrocarbon alkylation and isomerization. Catalysts are not active towards reactants across their entire surface; only specific locations possess catalytic activity, called active sites. The surface area of a solid catalyst has a strong influence ...

  4. Methane functionalization - Wikipedia

    en.wikipedia.org/wiki/Methane_functionalization

    Another example of acetic acid synthesis was demonstrated by Pombeiro et al., which used vanadium-based complexes in trifluoroacetic acid with peroxodisulfate as the oxidant. [8] The proposed mechanism involves a radical mechanism, where methane is the methyl source and trifluoroacetic acid is the carbonyl source.

  5. Molecular model - Wikipedia

    en.wikipedia.org/wiki/Molecular_model

    Beever's ball and stick model of ruby (Cr-doped corundum) made with acrylic balls and stainless steel rods. However, most molecules require holes at other angles and specialist companies manufacture kits and bespoke models. Besides tetrahedral, trigonal and octahedral holes, there were all-purpose balls with 24 holes. These models allowed ...

    More examples of substrate-controlled, anti-Markovnikov Tsuji-Wacker Oxidation of olefins are given in reviews by Namboothiri, [40] Feringa, [36] and Muzart. [ 41 ] Grubbs and co-workers paved way for anti-Markovnikov oxidation of stereoelectronically unbiased terminal olefins, through the use of palladium-nitrite system (Figure 2, D). [ 42 ]

  7. Methanium - Wikipedia

    en.wikipedia.org/wiki/Methanium

    At about 270 Pa of pressure and ambient temperature, the methane ion CH + 4 will react with neutral methane to yield methanium and a methyl radical: [11] CH + 4 + CH 4 → CH + 5 + CH 3 • The methanium ion can also be made in the gas phase via the reaction of methane and an H + ion (i.e. a proton). [citation needed] CH 4 + H + (g) → CH + 5

  8. Space-filling model - Wikipedia

    en.wikipedia.org/wiki/Space-filling_model

    A space-filling model of n-octane, the straight chain (normal) hydrocarbon composed of 8 carbons and 18 hydrogens, formulae: CH 3 CH 2 (CH 2) 4 CH 2 CH 3 or C 8 H 18.Note, the representative shown is of a single conformational "pose" of a population of molecules, which, because of low Gibbs energy barriers to rotation about its carbon-carbon bonds (giving the carbon "chain" great flexibility ...

  9. 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 ...
