Catalyst Carrier

Sulfur Recovery Catalyst Characteristic The catalyst is a highly specific surface active Al2O3-based Claus sulfur recovery catalyst. Its comprehensive performance and technical indicators have reached the international advanced level. ■ Has a large specific surface area and high strength properties; ■ The catalyst particles are uniform and the wear is small; ■ High catalyst activity and good stability; ■ The pore structure is bimodal, which is more conducive to process gas diffusion and Claus reaction; ■ Long catalyst life. Use and conditions of use The Claus sulfur recovery unit for petrochemical and coal chemical industries can be used in all grades of Claus reactors or in layers with other functions or types of catalysts. ■ Temperature: 220～350°C ■ Pressure: ~0.2MPa ■ Airspeed: 200~1000h-1 Physical and chemical properties Appearance U nit W hite S phere Dimensions mm Ф 4 ～Ф 6 Al2O3% m/m ≥ 90 Surface area m2/g ≥ 300 Pore ​​ volume ml/g ≥ 0.40 Bulk density kg/L 0.65 ～ 0.80 Resistance to crushing N/particle ≥ 140 Packaging, storage and transportation ■ Packed in woven bags, lined with plastic bags, 40kg per bag (or according to user requirements). ■ During the transportation process, you should pay attention to moisture, avoid rolling, bumping and other intense shocks, and should have rainproof facilities. ■ The catalyst should be stored in a dry and ventilated warehouse to prevent contamination or moisture.
