Hello,
I could not find the solution on google- does anyone know the temperature required for the water-gas reaction to work (C + H2O -> CO + H2)? Also, are there any catalysts which may improve the result or lower the reaction temperature?

Isn't the reaction CO (g) + H₂O (g) <-> CO₂ + H₂ ?

It is known as steam reformation too.

The water-gas reaction in particular is C_(s) + H₂O_(l) ==> CO_(g) + H_2(g).  It needs 800°C temperature to work.

I found a cool movie of the reaction at http://128.104.70.28/demonstrations/Gen_Chem_Pages/06thermopage/water_gas_reaction.htm (for those who think it may be boring..it's not!  I didn't expect it to be exciting either, but apparently it's vigorous!)

And what geodome gave is indeed called steam reforming...it isn't water-gas, but it's VERY similar (equation wise, anyways)

And as for catalysts, apparently there are catalysts that can lower this temperature requirement to 283°C...if you have access to journals, you can read about it at White, E.C., Schultz, J.F.  Fused Cobalt Oxide as a Water-Gas Catalyst.  Ind. Eng. Chem., vol. 26, 1934, pp. 95-97.

And finally, these water-gas catalysts are apparent a HOT item right now, because they're applicable to fuel-cells (somehow).  Corporations are getting papers published after coming up with a few (and probably patenting them of course lol)...but this is a good article about them from Engelhard Corp: http://www.engelhard.com/documents/EC%20paper%20in%20Journal%20of%20Power%20Sources2002.pdf

And P.S. I think that article has been reproduced illegally by Engelhard Corp...I thought Elsevier became the owner of any submitted articles   Mod/Admin opinion on this?

Hopefully all this helps you out   Good luck

cool video! Can't say I'd exactly be thrilled to carry it out in a semi-closed container like that, though

Ah! Thanks a lot, sorry for the delay in response. I'm confused though, do you have any idea which Cobalt Oxide it is (there is cobalt (II) oxide and cobalt (III) oxide which both go under the same name). I suppose I could experiment with both, thanks for the *delete me*
