Catalytic properties of Ru-mordenite for NO reduction
Original language description
The reduction of NO by CO over H and Na forms of Ru exchanged mordenite has been studied with ruthenium content of 0.2, 1 and 3 wt.percent. The catalysts were characterized with respect to X-ray diffraction, BET surface area, temperature programmed oxidation, and temperature programmed desorption of ammonia. These catalysts have been evaluated for their activity for NO-CO reaction using a steady state gas laboratory evaluation assembly. The catalysts show high activity for NO reduction and almost 100 percent conversion of NO to N-2 was observed below 400 degrees C. The activity was found to be a factor of ruthenium content, however, Ru-mordenite in Na form was observed to be relatively more active than Ru-mordenite in H form, probably due to the electron donation from sodium to ruthenium sites.

Katalytické vlastnosti Ru-mordenitu pro redukci NO
Czech description
Byla studována redukce NO pomocí CO na katalytických systémech na bázi Ha Na formy mordenitu nasycené rutheniem; obsah Ru byl 0.2, 1 a 3 procent. Katalyzátor vykazoval vysokou aktivitu pro redukci NO n N2, podařilo se dosáhnout prakticky 100 procent konverzi při teplotách do 100 stupňů C.
