Hydroxylated iron oxide desulphurisation agents are high-sulphur-capacity desulphurisation agents produced using our company’s industrially synthesised light-base iron oxide as the active component, combined with special additives and advanced manufacturing processes, with a breakthrough sulphur capacity exceeding 30%. They are characterised by high sulphur capacity, high desulphurisation efficiency and rapid reaction rates.
1. Product Description
Hydroxylated iron oxide desulphurisation agents are high-sulphur-capacity desulphurisation agents produced using our company’s industrially synthesised light-base iron oxide as the active component, combined with special additives and advanced manufacturing processes, with a breakthrough sulphur capacity exceeding 30%. It features high sulphur capacity, high desulphurisation efficiency and rapid reaction rates, and is widely used for the removal of hydrogen sulphide from gases such as natural gas, associated petroleum gas, coalbed methane, shale gas, blast furnace gas, coke oven gas, biogas and sulphur-containing tail gases from petroleum refining. The product’s high sulphur capacity effectively reduces secondary pollution and the frequency of replacement.
