Catalysts

Sienna-SSD expands its patented  SSC-line of high temperature catalysts and now offers  SSC-111, SSC-210, SSC-211,  and SSC-220 catalysts for hot burning N2O-based and HAN-based advanced green monopropellants.  

Sienna-SSD has developed an industry leading high temperature catalyst for decomposition of hot burning advanced green monopropellants for chemical propulsion and gas generators. Sienna-SSD’s SSC-111 catalyst has been successfully tested with a HAN-based highly energetic advanced green monopropellants. Sienna SSC-111 catalyst has reduced pre-heat temperature from the State-of-Art 425oC to 265oC. This is a significant accomplishment since it also reduces power required to pre-heat the catalyst bed.

Sienna-SSD’s SSC-104 catalyst is also very active for Nitrous Oxide (N2O) decomposition. N2O is considered as a potential monopropellant for chemical propulsion and gas generators. Our SSC-line of catalysts have almost perfectly spherical shape with a very narrow size distribution, thanks to a patent pending process technology, and high mechanical strength that they can be closely packed in thrust chambers.   We offer our SSC-line of catalysts in three different sizes, 14-18 mesh,  18-25 mesh, and 30-35 mesh. However, we can manufacture them to any size including extruded pellets and honeycomb monoliths as your application requires.
