Claus Catalysts

New generation of titanium dioxide (titania) catalysts offering one step further in SRU performances by increasing its porosity and lowering its density.

Titanium dioxide (titania) catalysts offer the ultimate SRU performances. Claus reaction, sulfation resistance, and conversion of CS2 and COS have established SulShine® CRS 31 as truly outstanding and, consequently, it has become the world’s leading high performance SRU catalyst.

Advanced alumina sulfur recovery catalyst SulShine® CR-3S is a high-purity-alumina catalyst available as 3-6 mm diameter beads. This superior Claus catalyst is characterized by its tailored ultra-macroporosity, excellent mechanical properties and improved diffusion properties.

SulShine® CR-400 is suitable for all converters and offers low loading density with low attrition loss and high mechanical strength.

The Standard Macroporous Claus Catalyst.

This alumina catalyst is for standard Claus feeds where the basic priorities are simple conversion of H₂S and when low pressure drop requirements are imposed.

For managing aromatics in Claus feeds: SulShine® CSM 31 is the selective hydrogenation catalyst developed expressly for use in association with SulShine® CRS 31 to achieve the highest COS and CS₂ and Claus conversions in streams containing aromatics.

Excessive oxygen in the feed results in bulk sulfate formation that eventually poisons the catalyst. SulShine™ AM catalysts mitigate bulk sulfate formation and increase catalyst service life typically by 50%.

Compared with SulShine™ AM catalyst, SulShine™ AMS offers a similar bed protection by oxygen scavenging. In addition, SulShine™ AMS provides a higher activity in Claus and COS/CS₂ hydrolysis reactions.
