WebThe 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 ) in the presence of a nickel catalyst.It was discovered by the French chemists Paul Sabatier and Jean-Baptiste Senderens in 1897. Optionally, … WebThis is a figure of methane sorption for a material his group made at different temperatures: Granted the highest uptakes are at high pressures (1 bar ~= 1 atm), and the graph is somewhat muddled at ~1 atm, but this material sorbs (much) more than its own volume at that pressure, and there are other examples.

Methane decomposition to produce hydrogen and carbon

WebJan 5, 2024 · The conversion reaction from CO 2 to graphite can occur in the absence of transition metal catalysts when the CO 2 ‒LiAlH 4 system is heated to as low as 126 °C, … WebAug 8, 2012 · React carbon-dioxide with hydrogen in the Sabatier process to get methane. 400 °C, high pressure and Nickel catalyst needed. The process is slighly exothermic so it can keep going on its own: $$\ce{CO2} + \ce{4H2} \rightarrow \ce{CH4} + 2\ce{H2O}$$ ...
