Abstract

Abstract: In this paper, a series of iron-based Fischer–Tropsch catalysts were prepared with mesoporous titanium dioxide as catalyst carrier. And the F-T catalytic activities of iron supported on the mesoporous TiO2 with different doping concentrations were also investigated in photo-thermal driven Fischer–Tropsch synthesis. Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), Low temperature N2 adsorption-desorption, X ray powder diffraction (XRD), Temperature Programmed Reduction (TPR) were used to characterize the catalysts, and the catalytic performance were also investigated for Photo-thermal driven Fischer–Tropsch synthesis under the condition of atmospheric pressure at the temperature of 220 °C, n (H2 )/ n (CO) = 2:1 and GHSV = 1500 h −1 . It is shown that, for different doping concentration of iron, the conversion of CO, the selectivity of methane and the selectivity of C2+ changes, resulting in the difference performance of Photo-thermal Fischer Tropsch synthesis reaction. Highlights: The Fischer–Tropsch synthesis is currently of increasing interest. Iron-based F-T catalysts were prepared with mesoporous TiO2 as catalyst carrier. Different Fe-doping amounts were investigated in photo-thermal driven FT syntheses.
