Abstract

A route for converting CO₂ into valuable products, such as plastic monomers, is the combination of methanol synthesis and methanol dehydration to hydrocarbons. Methanol synthesis is equilibrium limited and a strategy to overcome this is to combine a methanol synthesis catalyst with a zeolite catalyst within one reactor [1,2]. In the temperature range of 300 to 420 °C, necessary for the zeolite to be active, the traditional Cu/ZnO/Al₂O₃methanol synthesis catalyst cannot be used due to severe sintering of the metallic copper deactivates the catalyst. Furthermore, the hydrogen spill-over effect and likely surface reactions on the metallic copper result in the hydrogenation of the olefins formed in the zeolite [3].
