Analysis of reasons for decline in activity of palladium catalyst for anthraquinone hydrogenation in industrial plant and discussion of treatment measures
The production process of hydrogen peroxide is briefly introduced.The possible reasons that may cause the decrease of palladium catalyst activity,such as high moisture content in the working solution,covering with alumina powder and agglomeration of palladium catalyst,etc.are emphatically introduced.The activity of palladium catalyst can be gradually recovered by process adjustment measures,such as adding the water removing equipment for the working solution and the activated alumina bypass filtration system,and using the high performance palladium catalyst,etc.
