Développement et optimisation de catalyseurs à base de cuivre pour la synthèse de méthanol et de diméthyléther à partir de CO2

Abstract : Reducing CO2 emissions, the main greenhouse gas, is one of the major challenges of our current era. Many measures already exist but are still insufficient. It is in this context that the ANR project called DIGAS was funded. During this work, catalytic materials composed of CuO/ZnO/ZrO2 were developed by classical coprecipitation and tested under a pressure of 50 bar for the methanol synthesis from CO2 hydrogenation. Then, these catalysts were optimized using a system developed in the laboratory: microfluidic continuous synthesis. It has made the catalysts more homogeneous and thus more efficient. The most efficient catalyst was subsequently coupled to a ZSM5 zeolite to allow direct dimethyl ether (DME) synthesis from the CO2 hydrogenation. In the case of methanol as well as for DME synthesis, the developed catalysts are competitive and more efficient than the catalysts currently on the market.
