Abstract: Based on the synthetic principle of CuO/ZnO/Al2O3 catalysts，the possibility and existing problems of using high-gravity rotating packed bed in reactions with gas-liquid-solid three-phase products were studied. A suggestion for improvement was proposed，based on which a large-scale high-gravity rotating packed bed with 50 t/a yield was founded and used for catalyst preparation. Characterization results for the catalysts showed that all the physical properties are superior to the existing aldehyde hydrogenation catalysts.

摘要： 通过讨论CuO/ZnO/Al2O3催化剂的合成机理研究了超重力旋转床制备产物为气-液-固三相的材料的可行性以及存在的问题，并提出了解决办法，在超重力旋转床改造意见的指导下建造了年产50 t的CuO/ZnO/Al2O3催化剂的大型超重力机并用于催化剂的制备。催化剂的表征结果表明，所制备的催化剂的各项理化性能优于现有的醛加氢催化剂。
