Vanadium pentoxide series of sulfuric acid catalysts could 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 S108 is low temperature catalysts which suit for 1/3 top of the first bed to decrease inlet operating temperature, and 4th bed, 5th bed to improve equilibrium conversion and decrease gas emission.
On the basis of modified formulation and improved manufacturing process, we successfully developed the S108 series improved vanadium catalyst, a new version of low temperature catalyst. It requires less start-up time, and offers higher activity under low temperature conditions. Due to its higher surface area and porosities, the product ensures improved conversion rate of sulfur dioxide.
Compared with the products of our domestic competitors, the improved vanadium catalyst has advantages that it offers lower loading coefficient, higher activity and longer service life so as to achieve the cost effective investment.
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.
