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 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 ...
[50] [51] Methane pyrolysis is the process operating around 1065 °C for producing hydrogen from natural gas that allows removal of carbon easily (solid carbon is a byproduct of the process). [ 52 ] [ 53 ] The industrial quality solid carbon can then be sold or landfilled and is not released into the atmosphere, avoiding emission of greenhouse ...
However, this means that tar and methane production is significant at typical operation temperatures, so product gas must be extensively cleaned before use. The tar can be recycled to the reactor. In the gasification of fine, undensified biomass such as rice hulls, it is necessary to blow air into the reactor by means of a fan. This creates ...
Methane is also subjected to free-radical chlorination in the production of chloromethanes, although methanol is a more typical precursor. [35] Hydrogen can also be produced via the direct decomposition of methane, also known as methane pyrolysis, which, unlike steam reforming, produces no greenhouse gases (GHG). The heat needed for the ...

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 ...
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 ...
