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: Broad Temperature Type of Sulfuric Acid Catalyst: S101.

1. Type S101: Type S101 series are broad temperature catalysts which suit for every bed of converter.

There are four products of type S101, in details, they are S101 (Cylinder); S101-H (Ring); S101-MH (Star ring); S101-YH (Three-Ribs Cylinder).

Type S101 Catalyst is a medium broad temperature vanadium catalyst which promotes the oxidation from SO2 to SO3, and it is developed by China. With 20 years of manufacturing S101 catalyst, it has reached the international advanced level. Due to its high-quality and steady performance,

The advantages of S101 are as listed.

Wide applicability, broad range of temperature, high conversion, and high mechanical strength etc. Ring or plum blossom shaped catalysts have solved some problems that cylinder shaped catalyst encountered; namely, they are small pellets, high pressure drop and high energy consumption, bad resistance of dust accumulation.

2: 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 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.

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.
