Recent advances in cobalt-based Fischer-Tropsch synthesis catalysts
Yujun Suo,Yali Yao,Yusheng Zhang,Sijia Xing,Zhong-Yong Yuan 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.115 No.-
Fischer-Tropsch synthesis (FTS) is a promising technology for converting renewable energy sources tosynthetic liquid fuels, olefins or oxygenates. As one of the metal-based FTS catalysts with excellent intrinsicactivity, supported Co-based catalysts have attracted much attention. Their properties depend on theirgeometric morphology, surface composition and metal-support interaction (MSI). This paper reviews thelatest research progress of the supported Co-based catalysts for FTS, including recently-developed functionalmodification strategies to adjust the cobalt phase, crystallite size, metal dispersion, site density andmetal-support interaction to optimize the performance of cobalt-based catalysts. The effects of importantmaterials (including cobalt precursors, supports and promoters) on catalytic performance are discussedand compared. A summary is provided of the modifications made to catalysts with a unique and controllablestructure, in order to improve the catalytic activity and focus the product distribution on targetedwax, gasoline, diesel, olefins and oxygenate products. Guidance is provided regarding controlling thestructure and functions of Co-based catalysts. Opportunities and perspectives on future research intomodification strategies used for Co-based FTS catalyst are also noted.
