Abstract

ZnO supported on zirconia (ZnO/ZrO2) catalyses methanol synthesis with high selectivity and stability at temperatures >300 °C. When combined with H-ZSM-5 a CO2 conversion of 14-15 % with an aromatics selectivity of 73-76 % has been reported [1,2]. This work investigates the combination of ZnO/ZrO₂ with ZSM-5 of various acid site densities, for the direct conversion of syngas to aromatics. The mixing ratio and operating conditions were optimized to increase the CO_xconversion and aromatics selectivity. This includes fundamental characterization using BET, ICP and XRD and in-depth characterization using in-situ XAS and DRIFTS.
