Claus Catalysts
UOP’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 (UOP product numbers S-201 and S-2001); and titania catalysts (UOP product number S-7001).
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.
The UOP S-201 catalyst delivers excellent results when H2S is the primary compound
to be removed from the feed gas. Our new-generation activated alumina Claus
catalyst, S-2001, combines high macropore volume and BET surface area with
exceptional physical strength and abrasion resistance. S-2001 is of special
interest in sub-dewpoint processes where higher macropore volume is especially
important. S-2001 is also more effective for COS and CS2 conversion than S-201,
and is therefore preferable for use in the first reactor of a typical Claus
plant.
The UOP S-7001 titanium dioxide based Claus catalyst has excellent physical
characteristics and a unique pore structure that allows for high rates of diffusion
of reactants and products. It is available in tablets. As an advanced, high
performing sulfur recovery catalyst, S-7001 is well suited for maximizing the
conversion of COS and CS2 in the first converter. In the second and third
converters,
it is very beneficial due to its resistance to sulfur poisoning and longevity
in maintaining high H2S/SO2 conversion.
