 CHEMPACK's Claus catalysts are considered the industry standard for delivering improved sulfur recovery. They are used as sulfur recovery catalysts in natural gas plants, refineries, and smelters. They perform well in facilities that employ Claus process plants, as well as other types of sulfur recovery plants. These spherical activated aluminas and titania-based catalysts have high surface area and purity, low bulk density and high macroporosity. These properties ensure maximum activity for the conversion of sulfur compounds. Two main types of catalysts are used in conventional Claus units: activated alumina(CHEMPACK product numbers PSR-1 which equivalent to CR-3S ); and titania catalysts (CHEMPACK product number PSR-21 and PSR-31 which equivalent to CRS-21 and CRS-31). They vary in their capability to hydrolyze COS and CS2 and to resist poisoning (sulfation). These Claus catalysts may be used alone or in combination beds, depending upon performance requirements.
