“…Promoters are crucial for FTS catalysts, as they can enhance activity, stability and selectivity. [5] Co-based FTS catalysts usually contain noble metal promoters, [5,111] which can promote the reduction of metal oxides into active metal particles, thus lowering the temperature during the activation and regeneration procedures, and limiting oxidation during the FTS. [111] Moreover, noble metal promotion can also affect the catalytic properties under relevant FTS conditions.…”

Carbon capture and utilization represents a promising strategy to meet the global energy and climate goals. Under specific conditions, CO2 catalytic hydrogenation with renewable H2 can transform waste CO2 into a chemical feedstock for added‐value energy carriers and chemicals. CO2‐Fischer–Tropsch synthesis‐based‐hydrocarbons should contribute to the creation of a circular carbon economy with a significant impact on anthropogenic emission into the atmosphere. This review summarizes the progress achieved toward the single‐step hydrogenation of CO2 to long‐chain hydrocarbons over oxide‐supported Co‐based catalysts. Mechanistic aspects are discussed in relation to thermodynamic and kinetic limitations. The main parameters that must be taken into consideration to increase the activity and the selectivity toward compounds of two or more carbon atoms (C2+) are discussed in detail: cobalt active phase, support and metal‐support interfaces, and promoters. Finally, particular focus is dedicated to the role of reducible oxide supports and their surface defects on the activation of CO2, as well as on the regulation and evolution of metal‐support interactions.

“…The overall suboptimal catalytic performance of raw iron ore compared to the conventional precipitated LTFT catalysts was attributed to the precursor's deficient physicochemical properties (raw iron ore). The promotion of iron catalysts, in general, should improve the properties of the ores and, in turn, improve their overall catalytic performance [4,9,11,12,18,19,24,30,[55][56][57][58]. There was an exception with the fresh iron ore studied by Ramutsindela et al [2] and Kulikova et al [7] due to impurities such as magnesium, which other natural iron ore reported by previous authors did not have.…”

The use of iron ore as an alternative to conventional Fischer–Tropsch synthesis (FTS) iron catalyst has been identified as a way to achieve a cost-effective catalyst. In recent times, considerable progress has been made to build a strong case for iron ore as a viable alternative to traditional iron catalysts. Nevertheless, there are still opportunities to enhance the current iron ore low-temperature Fischer–Tropsch (LTFT) catalysts and pave the way for optimal performing catalysts. In this study, we thoroughly examined the various publications on iron ore catalysts used for FTS and highlighted the research gaps in the studies. The study identified the progress made so far, opportunities, and challenges regarding the use of iron ore as a catalyst in FTS. One of the critical areas that needs to be addressed from the review is establishing the deactivation pathways of these catalyst systems. The application of advanced spectroscopic and computational methods is also suggested to elucidate the relationship between the synthesis conditions, active catalytic sites, reaction intermediates, and catalytic performance to fabricate optimized iron ore LTFT catalysts.

“…Sustainable Fischer-Tropsch synthesis (FTS), utilising energy and gas derived from renewable energy sources (RES), such as biomass gasification [2,3], could play a non-negligible role in this transformation. The Fischer-Tropsch synthesis is thoroughly examined physical-chemical process, and numerous studies were already published on catalytical substances [4][5][6][7], process parameters [6,8,9] or applications [10][11][12]. Usually, Fe catalysts [13] or less sustainable and more toxic Co catalysts for better reaction activity are used [14].…”

Background Despite the sufficient description of the various catalytic processes, the data sets often lack a long-term oriented approach, thus examining unstable and temporary processes. Results In this study, an Al2O3-supported Co catalyst was applied in a small-scale Fischer-Tropsch synthesis under realistic conditions. A long-term performance was examined and evaluated. A tedious stabilisation regime was observed, taking around 78 hours of time-on-stream before the process was stabilised on a greater magnitude. The quantitative analysis showed significant differences in liquid production, where unstable process provided more excellent gas-to-liquid conversion, however, the selectivity of water was significant. The stabilised regime, on the other hand, performed well in terms of hydrocarbon production with 35%wt. share in the product. Conclusions This study points out the importance of proper stabilisation in the catalytic processes, which may require reasonable time in pilot and industrial-scale appliances.
