超重力反应器用于产物为气-液-固三相的催化剂制备

Preparation of catalyst with gas-liquid-solid three-phase products using high gravity reactor

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50t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。

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.
