  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. Four-carbon molecule - Wikipedia

    en.wikipedia.org/wiki/Four-carbon_molecule

    Four-carbon molecules are based on a skeleton made from four carbon atoms. They may be in a chain, branched chains, cycles or even bicyclic compounds C 4 H 4 isomers with CAS registry numbers

  4. Acetylene - Wikipedia

    en.wikipedia.org/wiki/Acetylene

    Acetylene (systematic name: ethyne) is the chemical compound with the formula C 2 H 2 and structure H−C≡C−H. It is a hydrocarbon and the simplest alkyne. [8] This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. [9]

    The molecular formula C 4 H 2 (molar mass: 50.06 g/mol, exact mass: 50.01565 u) may refer to: Diacetylene , or butadiyne Propalene , or bicyclo[1.1.0]buta-1,3-diene

  6. Haber process - Wikipedia

    en.wikipedia.org/wiki/Haber_process

    The process was purchased by the German chemical company BASF, which assigned Carl Bosch the task of scaling up Haber's tabletop machine to industrial scale. [5] [11] He succeeded in 1910. Haber and Bosch were later awarded Nobel Prizes, in 1918 and 1931 respectively, for their work in overcoming the chemical and engineering problems of large ...

  7. Methanation - Wikipedia

    en.wikipedia.org/wiki/Methanation

    Methanation is an important step in the creation of synthetic or substitute natural gas (SNG). [7] Coal or wood undergo gasification which creates a producer gas that must undergo methanation in order to produce a usable gas that just needs to undergo a final purification step.

  8. Hydrogen - Wikipedia

    en.wikipedia.org/wiki/Hydrogen

    Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H 2, sometimes called dihydrogen, [11] hydrogen gas, molecular hydrogen, or simply hydrogen. It is colorless, odorless, [12] non-toxic, and highly combustible.
