Catalyst АОК-75-46
Process
Oxidation of hydrogen sulfide to sulfur (Claus process), hydrogenolysis of organosulfur compounds
Product Type
Titanium dioxide catalyst is used as a base catalyst for acid gas treatment in refining and gas processing industry, petrochemicals and metal manufacturing. More than 8 years of commercial experience.
Catalyst АОК-75-46 is available in cylinder extrudates.
Advantages
Catalytic activity and properties at a level of worldbest counterparts
High conversion of COS/CS2 in the temperature range of 260-350°С
High resistance to sulfate and HC poisoning
High resistance to water vapor (hydrothermal aging) at 450°С
Minimum service life is 4 years due to improved surface area and optimal porous structure
Can be used in acid gas treatment by direct oxidation of hydrogen sulfide to sulfur
Manufactured in Russia using proprietary technologies
Application
Catalyst АОК-75-46 is applied as the fixed bed at various Claus sulfur recovery units (SRU). Titanium dioxide catalyst, loaded into the first reactor, significantly extends the service life of the catalytic system. Applying AOK-75-46 in SRU II and III reactors ensures the maximum service life of the catalyst.
