PROCEDES D'OBTENTION DE GAZ COMBUSTIBLE A PARTIR D'ELECTROLYSE DE L'EAU (EHT) OU DE CO-ELECTROLYSE AVEC H2O/CO2 AU SEIN D'UNE MEME ENCEINTE, REACTEUR CATALYTIQUE ET SYSTEME ASSOCIES

摘要

The invention relates to a novel reactor design, wherein the pressurised chamber contains both a high-temperature electrolysis (HTE) reactor with elementary electrolysis cell stacking for producing either hydrogen or a synthesis gas (“syngas” for a H2+CO mixture) from water vapour H2O and carbon dioxide C02, and at least one catalyst arranged at a distance and downstream of the outlet of the electrolyser for converting the previously produced synthesis gas into the desired combustible gas, by means of heterogeneous catalysis, the synthesis gas having being produced either directly from the electrolysis reactor or indirectly by mixing the hydrogen produced with carbon dioxide C02 injected into the chamber.
