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.
