Extruded titanium dioxide (TiO2) Claus SRU catalyst for very high hydrolysis conversion of CS2 and COS to H2S and superior resistance to sulfation poisoning. Typically loaded in a portion of the first reactor. Superior resistance to sulfation poisoning and hydrothermal aging effects allow the catalyst to provide long service life while maintaining very high conversion. The resistance to sulfation may be beneficial in the second and third reactors, especially downstream of direct-fired reheaters, or in cases where the potential for sulfation poisoning exists. Allows higher space velocities for the same sulfur conversion, which may result in smaller Claus SRU reactor volumes for new or retrofit units.

Extruded titanium dioxide (TiO2) Claus SRU catalyst for very high hydrolysis conversion of CS2 and COS
to H2S and superior resistance to sulfation poisoning. Typically loaded in a portion of the first reactor.
Superior resistance to sulfation poisoning and hydrothermal aging effects allow the catalyst to provide
long service life while maintaining very high conversion. The resistance to sulfation may be beneficial
in the second and third reactors, especially downstream of direct-fired reheaters, or in cases where the
potential for sulfation poisoning exists. Allows higher space velocities for the same sulfur conversion,
which may result in smaller Claus SRU reactor volumes for new or retrofit units. Claus SRU units requiring
a TiO2 catalyst may have one or more of the following conditions:
• Feeds with high COS and CS2
• Located in regions with higher sulfur emissions standards
• Need to decrease turnaround frequency (increased active life)
• Plants with lean acid gas feeds
• Claus SRUs followed by sub-dew point, SUPERCLAUS®, directoxidation, or no tail gas treating
• Need to debottleneck downstream tail gas treating unit
to H2S and superior resistance to sulfation poisoning. Typically loaded in a portion of the first reactor.

Storage:
The material is stored in its original containers/packaging in a dry, covered location protected
from the ambient environment
• The material is protected from direct exposure to sunlight and rain (prolonged exposure to
direct sunlight may degrade the packaging)
• The material is not subjected to temperatures exceeding 450°F/230°C while in storage
• The material is stored elevated off the ground to ensure that there is no exposure to liquid
water
• Once the material is loaded into the vessel, a thorough nitrogen purge is recommended to
remove excessive free moisture
• Desiccant products intended for regenerative service will require a complete thermal
regeneration cycle (in TSA service) or several pressure swing cycles (in PSA service) before full
activity is restored
