Product Description
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.
For the fourth and fifth stage conversion, the common use amount of catalyst is 220-260L (t/d 100%H2SO4), while in the process of smelting gas-based acid production, the amount can be 1.6-1.8m3 (km3 gas/h), but under the condition of using plum blossom shaped or ring shaped catalyst, the amount can increase 10-20%, so as to make sure operating gas velocity more steady.
1). Type S101 series are broad temperature catalysts which suit for every bed of converter.
2). 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.
