How is Methane Produced from Hydrogen?

[swish4fish]

Puting aside politics and energy considerations, what is the chemistry of producing Methane from Hydrogen? What catalyst or special equipment would be needed? Thanks

Are you sure you want to produce methane from hydrogen, and not the opposite?!

Check making gasoline from coal (gasification), while that's not exactly the same, similar methods apply.

One could take hydrogen and CO2 and react it in the following manner (search "water gas shift"):

CO + H₂O <---> CO₂ + H₂

and combine it in the following sequence (search "Fischer-Tropsch"):

(2n+1)H2 + nCO → C_nH_(2n+2) + nH₂O
