PROCESS FOR PRODUCING COMPOUNDS OF THE C<SB>X</SB>H<SB>Y</SB>O<SB>2</SB> TYPE BY REDUCTION OF CARBON DIOXIDE (CO<SB>2</SB>) AND/OR CARBON MONOXIDE (CO)

摘要

The present invention relates to a process for electrolysing steam introduced under pressure into an anode compartment (32) of an electrolyser (30) provided with a proton-conducting membrane (31) made of a material that allows protonated species to be incorporated into this membrane under steam, water injected in steam form being oxidized at the anode (32) so as to generate protonated species in the membrane that migrate within this same membrane and are reduced at the surface of the cathode (33) in the form of reactive hydrogen atoms capable of reducing carbon dioxide and/or carbon monoxide, said process comprising the following steps: injection of CO2 and/or CO under pressure into the cathode compartment (33) of the electrolyser (30); - reduction of the CO2 and/or CO injected into the cathode compartment (33) by said reactive hydrogen atoms generated, in such a way that the CO2 and/or the CO form compounds of the CxHyOz type where x>1, y is between 0 and 2x+2 and z is between 0 and 2x.
