Direct conversion of synthesis gas to olefins (STO) is an attractive way of producing large volume base chemicals currently almost exclusively obtained from crude oil. It is a simplification of a two-step process of methanol synthesis followed by methanol to olefins (MTO), avoiding methanol condensation and purification and having fewer recycle streams.

Recent literature reports that a combination of different mixed metal oxides or supported metal oxides, such as ZnAl2O4, ZnGa2O4, ZnCr2O4, ZnO/ZrO2 or In2O3/ZrO2, can catalyze methanol synthesis at temperatures >380 °C where methanol dehydration to olefins can occur over narrow pore zeolites SSZ-13 or SAPO-34 [1-3].

However, literature is typically focusing on one type of each component. Here we report a comprehensive comparison between ZnAl2O4, ZnGa2O4 and ZnO-ZrO2 catalysts for methanol synthesis and for syngas to olefines when combined with SAPO-34. This includes fundamental characterization using BET, ICP and XRD and in-depth characterization using operando XAS and DRIFTS.
