S-Series Traditional Vanadium Catalyst
S-Series vanadium Catalyst is made from premium diatomite with several Optimal Selections, making itself a capable carrier of active element. Besides, the state-of-art reduction process makes it stronger in activity and thermal stability and multi-functional. Its different types, such as cylindrical, quincunx, ring, prism and hexagon, apply to all types of sulphuric acid converters.
