Sulfuric Acid Catalyst
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.
1). Type S101 series of broad temperature catalyst
The ignition temperature is 400℃. For continuous operation, the temperature should be in the range 420-620℃, which is suitable for each bed of converter for its high and stable activity.
2). Type S108 series of low temperature catalyst
The ignition temperature is 380℃ and operating temperature 400-540℃, 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.
3). Type S112 series Cesium-promoted catalyst
Much lower ignition temperature, much higher low temperature activity, much wider temperature range, faster reaction rate and longer service life etc. The loading capacity could be reduced by about 15%. The total conversion rate can reach more than 99.9%.
