Summary: The conversion of syngas to liquid fuels and chemicals using Fischer-Tropsch synthesis is a promising alternative route. In this study, carbon-encapsulated nanoparticles were synthesized to control particle size and improve catalytic activity. The catalytic performance of these nanoparticles (Fe@C) was found to be superior to conventional carbon-supported nanoparticles (Fe/C). By tuning the particle size, a peak in iron time yield was obtained, suggesting that particle size plays a significant role in catalytic performance. This study provides insights into the size effect on Fe-based catalytic Fischer-Tropsch synthesis.

Summary: Fischer-Tropsch synthesis has been investigated over a commercial cobalt-based catalyst, showing a positive effect of water on catalyst activity and increased C(5+) selectivity regardless of the H2/CO ratio. Increasing conversion led to increased C(5+) selectivity, while higher conversions resulted in significantly enhanced selectivity to CO2.

Summary: Established biofuel examples show the potential for sustainable ways to reduce reliance on fossil fuels and mitigate negative effects. The biomass-to-liquid (BtL) route, particularly the Fischer-Tropsch (FT) process, offers a pathway for converting biomass into liquid biofuels. However, technical challenges and high costs still hinder commercial applications. This review synthesizes information on impurities generation and removal techniques in the gasification integrated into the Fischer-Tropsch process (G-FT), proposing a flexible gas cleaning sequence.

Summary: A series of Fe-Mn bimetallic catalysts with different pretreatment atmospheres were used for the Fischer-Tropsch synthesis (FTS). The structure of Fe-Mn bimetallic catalysts was analyzed and the effect of different pretreatment atmospheres on reduction efficiency was investigated. It was found that nitrided Fe-Mn catalysts exhibited better stability and higher light olefin selectivity.

Summary: The Fischer-Tropsch (FT) process is a promising method for producing liquid fuels and valuable chemicals through CO hydrogenation. Catalyst activity and product selectivity are influenced by parameters such as support and promoters, which affect metal-support interaction, crystallite size, and more. This paper reviews the history of the FT process, the impact of different supports and promoters on cobalt-based catalyst performance, and the importance of proper reactor design for handling the heat of the exothermic reaction.

Summary: This study investigated the effects of different acidic zeolites on the selective production of isoparaffins in Fischer-Tropsch synthesis. It was found that large-pore acidic zeolites tend to produce more multi-branched alkanes, while strong acid sites lead to over-cracking of long-chain hydrocarbons into short-chain hydrocarbons. The results provide insights for designing catalysts optimized for isoparaffin synthesis directly from syngas.
