Description
The increasing concentration of atmospheric CO₂ has significantly contributed to global climate change, necessitating the development of effective mitigation strategies. One promising approach is the catalytic hydrogenation of CO₂ into valuable chemical feedstocks, such as light olefins. Previous studies have demonstrated that catalyst formulations with Fe/Co = 1:2 and Fe/Zr = 10:1 molar ratios exhibit enhanced performance for CO₂ hydrogenation to light olefins. Building upon these findings, this study investigates the catalytic behavior of a novel Fe-Co-Zr trimetallic catalyst, which is expected to further improve efficiency and selectivity in CO₂ hydrogenation. The catalyst was synthesized based on the established Fe-Co 1:2 bimetallic system, with Zr incorporation aimed at enhancing stability and performance. The catalytic activity was evaluated in a fixed-bed reactor across a temperature range of 275–400°C, with product distribution analyzed via on-line gas chromatography (GC). The results indicate promising catalytic performance for light olefins production, highlighting the synergistic role of Fe, Co, and Zr in facilitating CO₂ conversion. This study provides valuable insights into the design and optimization of advanced catalysts for sustainable CO₂ utilization.
