摘要（英）：

The invention relates to a method for preparing a CuO/ZnO/Al2O3 catalyst. Mixed solution containing Cu, Zn and Al reacts with precipitant in a high-gravity rotating-bed reactor at a temperature of between 50 and 90 DEG C, wherein the molar ratio of the mixed solution containing Cu, Zn and Al is 3/2-8/0.5-1.5; the aqueous-solution molar concentration of the mixed solution is 0.5 to 1.5 mol/L; the aqueous-solution molar concentration of the precipitant is 1.0 to 3.0 mol/L; the rotating speed of the high-gravity rotating-bed reactor is 200 to 1,500 r/min; and the volume-flow ratio of the mixed solution containing Cu, Zn and Al to the precipitant is 1/1-1/2. The method can improve production efficiency by 30 percent, freely adjusts the particle size of copper as an active component in a range between 5 and 20 nm, and is capable of continuous production.
