Catalyst АОК-75-33
Process
Hydrogen sulfide oxidation (Claus Process)
Product Type
Catalyst is applied for hydrogen sulfide removal from natural and industrial gases in refineries and gas plants, petrochemicals and metal manufacturing. Iron-bearing catalyst АОК-75-33 (oxygen scavenger) protects active bed alumina catalyst against sulfate poisoning and ensures high performance in main Claus reaction.
Catalyst АОК-75-33 is available in spheres with average diameter 5 mm.
Advantages
Catalytic activity and properties at a level of worldbest counterparts
High resistance to hydrothermal aging at 450°С
Minimum service life is 2 years due to improved surface area and optimal porous structure
Narrow size distribution and high mechanical strength maintain low level hydrodynamic resistance
High resistance to HC poisoning
Manufactured in Russia using proprietary technologies
Application
Catalyst АОК-75-33 is applied at Claus sulfur recovery units (SRU) as the fixed bed to protect active bed alumina catalyst against sulfate poisoning and extend the service life of Claus alumina catalyst.
