Vanadium pentoxide is most often used for sulfuric acid production and finds an application in sulfuric acid manufacturing devices that make pyritic, sulfur, phosphogypsum and gases containing sulfur as raw materials. The sulfuric acid catalyst is also applicable for making sulfur trioxide in sulfonation process in organic chemical industry.

Chemical equation: 2SO2 O2 = 2SO3

Our company developed many types of sulfuric acid catalysts, including S101, S107, S108, S101-2H, S107-1H, S108-1H, S101-2HY, S107-1HY, S108-1HY, ST112 and ST121. Among them, S101, S101-2H and S101-2HY are medium-temperature type catalysts for sulfuric acid production.

More Information about Sulfuric Acid Catalyst
S101 sulfuric acid catalyst is our earliest catalyst for sulfuric acid production. It features stable properties, reliable quality and high universality, suitable for use in each reaction phase of converters.

Aside from inherent properties of S101, S101-2H and S101-2HY both have low resistance and strong anti-block capacity. The two types are extremely appropriate for large-scale sulfuric acid production devices and metallurgical off-gas processing systems. With the usage of them, system resistance, energy consumption and lifespan are all improved.

Our low temperature sulfuric acids include S107/S108, S107-1H/S108-1H and S107-1HY/S108-1HY. They are advised to be matched with medium-temperature catalysts. Known for low initiation temperature and high low-temperature activity, these catalysts reduces conversion time, shortens operation time, saves energy, improves conversion rate, increases sulfuric acid production and decreases the emission of poisonous substances.

For ST112 and ST121 catalysts, they are jointly developed by our company and scientific research institutes. They possess low initiation temperature and high low-temperature activity and can be used in the first reaction phase and second conversion phase in converters. After using the sulfuric acid catalysts, the operation time, energy consumption, conversion rate and gas emission are remarkably improved.
