Description
INTRODUCTION: Addressing climate change remains a critical global challenge, with the reduction of CO₂ emissions through catalytic hydrogenation offering a promising solution. This study extends previous research on Fe-Mn bimetallic catalysts for CO₂ hydrogenation, where an Fe/Mn molar ratio of 30:1 exhibited superior activity and selectivity for light olefin production. Building on these findings, the present work investigates the impact of support materials on catalytic efficiency.
METHOD: Various supports, including CeO₂, Al₂O₃, SiO₂, TiO₂, ZrO₂, and ZSM-5, were incorporated into the Fe/Mn = 30:1 solution mixture, and the supported Fe-Mn catalysts were synthesized using the solvent evaporation method. The catalysts were then evaluated for CO₂ conversion to light olefins in a flow bed reactor at controlled temperatures (275–400°C), with product analysis conducted via an online gas chromatograph (GC).
CONCLUSION: Results indicate that catalytic performance is highly dependent on the choice of support material. These findings provide valuable insights into the role of supports in enhancing the efficiency and selectivity of Fe-Mn catalysts for CO₂ hydrogenation to light olefins and other value-added compounds.
