Methane to CO2 conversion

  1. Oct 30, 2011 #1
    I would like to convert methane to carbon dioxide without using combustion. The aim is to generate as little heat through the process as possible. Any ideas how this might be achieved would be appreciated.

    Cheers

    Look for a suitable catalyst/process. Try looking up platinum, palladium, rhodium and I think someone was working on, even, a nickel-tin 'nanotech' catalyst some time ago.

    What else do you want from the process; water (you'll get lots of heat out, it is quite (the most?) exothermic!), hydrogen, methanol? I guess there are particular processes and catalysts for all these reactions, and more.

    Thanks for the reply. Heat is ok, Its more the radiation heat from the flame I'm trying to avoid. I'm not to concerned about producing other specific products, I just want to eliminate an explosive atmosphere, and burning the methane is not practical within the confines of the work area.

    You can use methane oxidizing bacteria (Methylococcus capsulatus for eg.) if you can catch hold of some by any means.

    What about reacting with ozone? Under UV?

    Actually, methanoic acid can be oxidised to water and carbon dioxide efficiently. To do that, first, you need to substitute a halogen. e.g reacting with chlorine under UV. Then use NaOH solution to subsititute OH via nucleophilic mechanism. Treat it with some oxidising agent to produce methanal and methanoic acid and lastly CO2
