Product Overview


About Sulfur Recovery

Sulfur recovery is an important process for natural gas processing plants and refineries. The raw feed streams often contain gases, such as H2S and CO2. H2S is a highly toxic gas and contributes to SO2 emissions. To comply with environmental regulations, the sulfur species are converted to elemental sulfur and water via sulfur recovery technologies such as Claus Sulfur Recovery Units and Tail Gas Treatment Units.

Xintao is a 20 years experience manufacturer that has the most extensive line of Claus Catalysts in the catalyst industry. Xintao has high-quality products, proven technologies, and reliable services to meet your expectations and requirements.

TiO2 Based Sulfur Recovery Catalyst is a new kind of TiO2 based catalyst with special additives for sulfur recovery. Its comprehensive performances and technical indexes have reached world advanced level, and it’s in the leading position in domestic industry.



Here are some advantages of TiO2 Catalyst:

  • Higher activity for hydrolysis reaction of organic sulfide and Claus reaction of H2S and SO2, nearly approaching to thermodynamic equilibrium.

  • Claus activity and hydrolysis activity not affected by “leaked O2”. 

  • High activity,suitable for high space velocity and smaller rector volume.

  • Longer service life without the formation of sulfate due to process fluctuation with the regular catalysts.


XINTAO's Catalysts division is the world's leading supplier of environmental and process catalysts. XINTAO group offers exceptional expertise in the development of a wide variety of chemicals, adsorbents, catalyst and other products. By leveraging our industry-leading R&D platforms, passion for innovation and deep knowledge of precious , XINTAO's Catalysts division develops unique, proprietary solutions that drive customer success.


Applications and operating conditions

Suitable for Claus sulfur recovery units in petrochemical, coal chemical industry, also suitable for sulfur recovery of catalytic oxidization process e.g. Clinsuef, etc. It can be loaded full bed in any rector or in combination with other catalysts of different types or functions. Used in the primary reactor, it can promote hydrolysis rate of organic sulfur, in secondary and tertiary reactors increase the total sulfur conversion.
