Methane pyrolysis [40] is an industrial process for "turquoise" hydrogen production from methane by removing solid carbon from natural gas. [41] This one-step process produces hydrogen in high volume at low cost (less than steam reforming with carbon sequestration ). [ 42 ]

The pyrolysis of methane can be expressed by the following reaction equation. [140] CH 4 (g) → C(s) + 2 H 2 (g) ΔH° = 74.8 kJ/mol. The industrial quality solid carbon may be sold as manufacturing feedstock, included in asphalt pavement, or landfilled. Methane pyrolysis technologies are in the early development stages at several companies as ...

Scanning electron microscope (SEM) image of carbon nanocones (maximum diameter ~1 μm) produced by pyrolysis of crude oil in the Kvaerner process. [2] The endothermic reaction separates (i.e. decomposes) hydrocarbons into carbon and hydrogen in a plasma burner at around 1600 °C. The resulting components, carbon particles and hydrogen, are ...
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.
