CARBON DIOXIDE HYDROGENATION TO METHANOL OVER Cu/ZnO/ZrO2/EAGS CATALYSTS

Abstract

To mitigate CO2 emissions, CO2 hydrogenation to methanol is a promising process for converting renewable energy into valuable fuels and chemicals. The significant challenge remains to achieve a highly active, selective, and stable catalyst acceptable in industrial processes. While Cu/ZnO/ZrO2 is a promising catalyst for unleashing methanol production, its industrial potential remains unfulfilled due to insufficient performance and stability. Consequently, EAGs have been introduced as an additive to bolster the catalyst's effectiveness. The objective of this research is to develop and characterize a Cu/ZnO/ZrO2 catalyst incorporated with EAG to investigate the impact of EAG addition on catalyst performance. The synthesis involved the preparation of catalysts with EAGs through the co-precipitation method, followed by comprehensive characterization using XRD, SEM, N2 physisorption, H2-TPR, and CO2-TPD techniques.
