Kinetic Analysis of CO2 Hydrogenation to Long-Chain Hydrocarbons on a Supported Iron Catalyst

Lucas Bruebach et al.

Summary: Studies have carefully investigated the kinetics of an alumina supported iron catalyst under specific conditions and derived new kinetic expressions to better reproduce experimental data. The H-assisted CO2 and H-assisted CO dissociation mechanisms have been identified based on recent mechanistic investigations.

Identifying Performance Descriptors in CO2 Hydrogenation over Iron-Based Catalysts Promoted with Alkali Metals

Qingxin Yang et al.

Summary: In this study, the mechanistic and kinetic effects of alkali metals on CO2 hydrogenation over Fe-based catalysts were elucidated through advanced characterization techniques and kinetic analyses. The electronic properties of iron in iron carbides were found to be influenced by the alkali metal promoters, which in turn affect the catalyst's ability to activate H-2, CO, and CO2. The electronegativity of the alkali metal promoter was successfully correlated with the rates of CO2 hydrogenation and individual steps of CO or CO2 activation.

Regulating iron species compositions by Fe-Al interaction in CO2 hydrogenation

Minjie Xu et al.

Summary: In this study, the Fe-Al interaction in Na promoted Fe-Al catalysts was regulated by controlling the calcination temperature, leading to various compositions of iron oxide and iron carbides. The reactivity of different phases was investigated using multiple characterization methods and computational calculations. A correlation between the compositions of iron species and the activity of the catalyst for CO2 hydrogenation to olefins was established.

Understanding reaction-induced restructuring of well-defined FexOyCz compositions and its effect on CO2 hydrogenation

Andrey S. Skrypnik et al.

Summary: This study provides fundamental knowledge for developing Fe-based catalysts for CO2 hydrogenation to higher hydrocarbons, with well-defined compositions prepared through controlled decomposition of iron oxalate. The research also elucidates the pathways from CO2 to CO, CH4, and higher hydrocarbons, establishing a correlation between reaction pathways and steady-state composition for tailored catalyst design and preparation. The best performing Fe-based catalyst achieves a selectivity to CH4 below 10%, with a selectivity to C2+-hydrocarbons around 50% at 25% CO2 conversion and 300 degrees C, with an olefin to paraffin ratio of 5.5 among C-2-C-4 hydrocarbons.

Revealing property-performance relationships for efficient CO2 hydrogenation to higher hydrocarbons over Fe-based catalysts: Statistical analysis of literature data and its experimental validation

Qingxin Yang et al.

Summary: The manuscript introduces a mathematical approach to identifying fundamentals affecting catalyst performance, providing guidelines for tailored catalyst design or reactor operation. Analysis of literature data identified the Pauling electronegativity of dopant for Fe2O3 as a descriptor for CO2 conversion and CH4 selectivity, while combining alkali and transition metals as promoters for Fe2O3 was found to enhance selectivity for C2+ hydrocarbons. The developed Mn-K/Fe2O3 catalyst hydrogenated CO2 into C2-C4 olefins with a selectivity of 30.4% at a CO2 conversion of 42.3%, and an overall selectivity to C(2+-)hydrocarbons of 83.1%.

Bifunctional Co-based Catalysts for Fischer-Tropsch Synthesis: Descriptors Affecting the Product Distribution

Angela Strass-Eifert et al.

Summary: This study aims to develop bifunctional catalysts to tailor the product spectrum in Fischer-Tropsch synthesis, combining advanced characterizations and experiments under industrial relevant conditions. The acidity and pore structure are found to have a significant impact on the product distribution in the FT and hydroprocessing reactions.
