Description

field of invention

[0001] The invention relates to an iron oxide-supported palladium catalyst, a preparation method and application thereof. Background technique

[0002] Due to their irreplaceable catalytic activity and selectivity, noble metal catalysts play an extremely important role in oil refining, petrochemical and organic synthesis. The precious metal palladium has excellent catalytic performance, and the application of palladium catalysts in the petrochemical industry even exceeds that of platinum catalysts. For example, catalytic reforming in petroleum refining, isomerization and dehydrogenation of alkanes and aromatics, selective hydrogenation in olefin production, and production of organic chemical raw materials such as acetaldehyde, vinyl acetate, and methyl methacrylate. Palladium catalyst is inseparable. In addition, palladium is an excellent catalyst or an important component of catalysts in various organic chemical reactions such as hydrogenation, oxidativ...
