Methanation process of carbon dioxide with hydrogen
Not to be confused with Sabattier effect.
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. It was discovered by the French chemists Paul Sabatier and Jean-Baptiste Senderens in 1897. Optionally, ruthenium on alumina (aluminium oxide) makes a more efficient catalyst. It is described by the following exothermic reaction:[2]
∆H = −165.0 kJ/mol
There is disagreement on whether the CO2 methanation occurs by first associatively adsorbing an adatom hydrogen and forming oxygen intermediates before hydrogenation or dissociating and forming a carbonyl before being hydrogenated.[3]
∆H = −206 kJ/mol
CO methanation is believed to occur through a dissociative mechanism where the carbon oxygen bond is broken before hydrogenation with an associative mechanism only being observed at high H2 concentrations.
Methanation reactions over different metal catalysts including Ni,[4] Ru[5] and Rh[6] have been widely investigated for the production of CH4 from syngas and other power to gas initiatives.[3] Nickel is the most widely used catalyst owing to its high selectivity and low cost.[2]
