Sulfuric Acid Catalyst

Vanadium pentoxide series of sulfuric acid catalysts could 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. Type S101 series are broad temperature catalysts which suit for every bed of converter. Broad Temperature Type of Sulfuric Acid Catalyst: S101.   1)      Type S101: There are four products of type S101, in details, they are S101 (Cylinder); S101-H (Ring); S101-MH (Star ring); S101-YH (Three-rib 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.   Main Physical Property                 Type Item S101 S101-H S101-MH S101-YH     Physical Property Shape Cylinder Ring Star ring Three-rib cylinder Color Deep yellow or red brown Deep yellow or red brown Deep yellow or red brown Deep yellow or red brown Diameter(mm) Φ 4.5-5.5 OD:9-11 ID:3-4 OD:12-13 ID: 3-4 Φ 4.5-5.5   Remark: The diameter and length mentioned above can be designed according to customer’s request.   Main Technical Index (HG/T2086-2013 Standards)   Item               Type S101 S101-H S101-MH S101-YH Activity ≥81 ≥86 ≥86 ≥86 Crushing Strength ≥70 ≥40 ≥40 ≥70 Attrition loss ≤5 ≤5 ≤5 ≤5 V2O5% ≥7.5 ≥7.5 ≥7.5 ≥7.5 Bulk Density 0.6-0.65 0.52-0.56 0.5-0.55 0.58-0.6
