Vanadium pentoxide series of sulfuric acid catalysts can be used in the process of sulfuric acid production, to be more specific, is the process of SO2+I/2O2---SO3. With the help of Vanadium Catalyst, the rate of conversion can be improved greatly. It can guarantee the air speed of operation to add 10-20% more when using type star ring catalysts or ring catalysts.
Vanadium catalyst can be applied in many fields, such as, sulfur-based acid production, pyrite-based acid production, nonferrous smelting gas-based acid production, gypsum-based acid production etc.
Type S101 series are broad temperature catalysts which suit for every bed of converter. Low Temperature Type Sulfuric Acid Catalyst: S108. Type S108: S108 Cylinder; S108-H (Ring); S108-MH (Star ring); S108-YH (Three-rib cylinder) Type S108 Series sulfuric acid catalysts are invented in early 80s by China. The advantages of them are outstanding. In general, they are low ignition temperature, high activity in low temperature, high-resistant crushed strength etc. If can be used together with medium temperature type catalyst, such as, S101, you can make more profits; for instance, high conversion, and lowering environmental pollution.
