    摘要: The present disclosure provides a microsphere of oxide in the shape of raspberry, an FT synthesis catalyst containing the same as a support, and their preparation methods and applications. The inventive microsphere of oxide in the shape of raspberry is a hollow microsphere with a large hole on the surface, wherein the hollow microsphere has a hollow structure inside, and the large hole and the hollow structure are connected to form a cavity with an open end, wherein the oxide in the microsphere of oxide in the shape of raspberry is one or more selected from the group consisting of alumina, silica, zirconia, magnesium oxide, calcium oxide and titania. The inventive microsphere of oxide in the shape of raspberry shows better mass and heat transfer characteristics, and has strength which is significantly higher than that of existing products with similar structures. The microsphere of oxide in the shape of raspberry can be prepared by using the oxide and/or a precursor thereof as raw materials. The preparation is simple, low in cost, high in efficiency and suitable for large-scale industrial applications. The inventive FT synthesis catalyst comprises a microsphere of oxide in the shape of raspberry as a support and an active metal component supported on the support, wherein the active metal component is one or more selected from the group consisting of Co, Fe, and Ru. The inventive FT synthesis catalyst solves the diffusion problem in FT synthesis reaction and improves FT synthetic performance.

    摘要: The present invention is a process for the conversion of aluminum oxide hydroxide (AlOOH) to aluminum oxide. 30 to 70 wt-% of AlOOH, 30 to 70 wt % ammonium hydrogencarbonate NH
    4 HCO
    3 and 0 to 20 wt-% water are combined to produce a mixture. This mixture is then cured at a temperature from 30° to 90° C to convert at least 5% of the AlOOH to a ammonium hydroxycarbonate (dawsonite - type) intermediate and then the dawsonite-type intermediate is decomposed at a temperature from 130° to 320° C to produce aluminum oxide. The aluminum oxide can be further calcined at 500° to 800° C to produce a gamma-theta phase alumina.
