Sulphuric acid catalyst (also named vanadium pentoxide catalyst) suits for that sulphuric acid plants use the contact process to promote the oxidation of SO₂ and O₂ to give SO₃.

Based on more than 30 year’s experience with sulfuric acid catalyst, our factory can manufacture several types of catalysts in different shapes and sizes, such as S101, S101-2H, S101-3MH, S101-3BZ, S108, S108-2H, S108-3MH, S108-3BZ, S107, S107-2H, S107-3MH, S109, S106. Our manufacturing technique is advanced. The carrier is treated by repulped stock processing, washed by hot concentrated acid, pretreatment of calcinations, and added several rare accessory ingredients, then molded by using advanced patent technology. The performance of our catalysts is excellent, with high activity, low ignition temperature, high mechanical strength, low losses of screening, and long life. As for star ring type of catalyst, it has advantage of large surface area, low pressure drop, and good resistance of dust accumulation.
