Is this possible: CO2 + C = 2 CO (catalyst, conditions)?

Question

This can turn greenhouse gas into fuel (CO is the starting point for Fischer-Tropsch reaction)

Answer 1

This reaction occurs in the Blast Furnace. Look it up.

Answer 2

Yes, it is a real reaction (though it is reversable so it should be written as CO2+C<---->2CO. It can be catalyzed by a number of metals or can occur thermally at elevated temperatures. It is endothermic so energy must be supplied from an outside source.

The CO can be converted to sygas (the actual starting point for Fischer-Tropsch reactions) through shift reactions with water. Syngas can be converted into a number of compounds including methanol, gasoline, etc. Eventually, however, when these are burned the carbon is converted back to CO2. Also, the external energy used to drive this conversion must come from somewhere and this source will also likely release CO2 as well.

Answer 3

Check the Boudouard equilibrium, which is sometimes used to synthesize industrial CO.
