Methanation is the conversion of carbon monoxide and carbon dioxide (CO x) to methane (CH 4) through hydrogenation. The methanation reactions of CO x were first discovered by Sabatier and Senderens in 1902. [1] CO x methanation has many practical applications.
Any mixture of methane and air will therefore lie on the straight line between pure methane and pure air – this is shown as the blue air-line. The upper and lower flammability limits of methane in air are located on this line, as shown (labelled UEL and LEL, respectively). The stoichiometric combustion of methane is: CH 4 + 2O 2 → CO 2 + 2H ...
The process is electrolysis of water by electricity to create hydrogen (which can partly be used directly in fuel cells) and the addition of carbon dioxide CO 2 (Sabatier reaction) to create methane. The CO 2 can be extracted from the air or fossil fuel waste gases by the amine process .

For a diatomic molecule, an MO diagram effectively shows the energetics of the bond between the two atoms, whose AO unbonded energies are shown on the sides. For simple polyatomic molecules with a "central atom" such as methane (CH 4) or carbon dioxide (CO 2), a MO diagram may show one of the identical bonds to the central atom. For other ...
Complete revamp, giving a better likeness to File:Methane-CRC-MW-3D-vdW.png. Gradients are vastly improved, as are the sizes and shapes of atoms. Uploading this way (rather than as a separate image) would save numerous edits to target articles. 17:03, 24 October 2006: 1,100 × 1,100 (5 KB) Dbc334
Using co-product to generate electricity is one strategy that might improve the overall carbon balance. Another thing that needs to be acknowledged is that environmental impacts can also come from water management, carbon dioxide handling, and nutrient supply, several aspects that could constrain system design and implementation options.
