Our good quality Sulfuric Acid Catalysis Used Vanadium pentoxide Catalyst is usually contains 5% ~ 10% vanadium pentoxide (V2O5), which is the main component with catalytic activity. In addition to vanadium pentoxide, the catalyst also contains potassium oxide (K2O) or sodium oxide (Na2O) as co-catalyst to increase the activity of vanadium catalyst. Diatomite (mostly silicon dioxide) is used as the carrier to increase the surface area of the catalyst's active component in contact with the gas. Some vanadium catalysts also contain substances such as tin oxide, antimony oxide, iron oxide and alumina

Basic information
Sulfuric Acid Catalysis Used Vanadium Catalysts are used in the sulfuric acid industry to efficiently oxidize sulfur dioxide (SO₂) to sulfur trioxide (SO₃), and are also applied in the synthesis of aniline black dyes, the production of organic chemical raw materials, and flue gas desulfurization and denitrification, among other fields. In industrial applications, it is necessary to control the temperature sensitivity of catalysts, optimize gas distribution through alloy meshes, and establish an activity attenuation monitoring system. Spent vanadium catalysts can recover vanadium oxides through processes such as ion exchange and leaching calcination, with a recovery rate of over 90%.
