摘要
The Fischer-Tropsch (FT) synthesis, characterized by its highly exothermic and high-throughput nature, traditionally yields a mix of C2+ hydrocarbons and C1 by-products, which adversely affect carbon utilization efficiency. Herein, we design a Fe-foam structured catalyst to selectively produce high-value olefins in FT process. The Na-Zn-Fe/Fe-foam catalysts are prepared through a hydrothermal synthesis method, where the FeC2O4 precursor is formed from Fe-foam, followed by addition of sodium and zinc modifiers. These catalysts achieve a remarkable olefin selectivity of similar to 80 % and a space-time yield of similar to 0.70 g g(cat)(-1) h(-1) at a CO conversion of 98 %, and further demonstrate outstanding stability. The structured catalysts, with expansive void volume and fully open network architecture, provide superior mass and heat transfer capabilities, and effectively mitigate the generation of CO2 and CH4, offering a significant advantage in FT synthesis. This work presents a new strategy for the development of efficient catalysts in high exothermic catalytic reactions.
