1 : Broad Temperature Type of Sulfuric Acid Catalyst: S101/S109.

1.Type S101: S101 Cylinder; S101-2H(Ring); S101-3MH(Star Ring); S101-3BZ(Three-Ribs Cylinder) Type S101 Catalyst is a medium broad temperature vanadium pentoxide catalyst to promote the oxidation of SO2 and O2 to give SO3, which is developed independently in China. This catalyst has a manufacturing history of over 40 years with high standard quality and steady performance, has reached international advanced levels, and won the honorary title in Shandong province and Ministry of Chemical Industry.
This catalyst has advantages of wide applicability, broad range of temperature, high conversion and high mechanical strength. Ring or star ring shaped catalysts have solved some problems with cylinder shaped catalyst, which are small pellets, high pressure drop and high energy consumption, bad resistance of dust accumulation.

2.Type S109 catalyst’s operation temperature is much wider, which can be continuously operated in the range of 390 ℃ -620 ℃. The activity of low temperature and the performance of heat-resistant is much better than traditional medium broad temperature type of catalysts. This catalyst can replace composition using of S101 series and S108 series in double-absorption plants, and much easier in loading and refilling of catalysts.
