A raspberry-like oxide microsphere and an FT synthetic catalyst containing the same as a support, and preparation methods therefor and applications thereof. The raspberry-like oxide microsphere is a hollow microsphere of which the surface is provided with a macro pore; the hollow microsphere has a hollow structure inside; the macro pore is communicated with the hollow structure to form a cavity having an opening at one end; the oxide in the raspberry-like oxide microsphere is selected from one or more of aluminum oxide, silicon oxide, zirconium oxide, magnesium oxide, calcium oxide and titanium oxide. The raspberry-like oxide microsphere has excellent mass transfer and heat transfer performances, and the strength thereof is significantly higher than that of the existing products having similar structures. The raspberry-like oxide microsphere can be prepared using the oxide and/or a precursor thereof as raw materials, and the preparation method is simple, low in cost, high in efficiency and suitable for large-scale industrial applications. The FT synthetic catalyst comprises the raspberry-like oxide microsphere as a support and an active metal component supported on the support, wherein the active metal component is one or more selected from Co, Fe and Ru. According to the FT synthetic catalyst, the diffusion problem of the FT synthetic reaction is solved and FT synthetic performance is improved. |
