Catalyst АОК-78-59
Process
Catalytic oxidation of hydrogen sulfide (Claus process)
Product Type
Alumina catalyst is applied as base catalyst to remove hydrogen sulfide from natural and industrial tail gases in refineries and gas plants, petrochemicals and metal manufacturing. More than 20 years of commercial experience.
Catalyst АОК-78-59 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-78-59 is applied as the fixed bed at Claus sulfur recovery units (SRU). The alumina catalyst can be loaded into all SRU compartments.
