Description
| - Katalytická účinnost Fe-MFI v oxidaci propanu pomocí N2O a O2. Všechny studované materiály vykazovaly mizivou aktivitu v přítomnosti kyslíku, zatímco v přítomnosti N2O bylo dosaženo až 20% výtěžku. Výsledky charakterizace pomocí EPR a UV-vis spektroskopií naznačují, že aktivní částicí je část dobře dispergovaných částic železa. (cs)
- The performance of Fe-MFI zeolites in N2O- and O2-mediated conversion of propane to propene and oxygenates has been investigated over a set of calcined and steamed Fe-MFI (Si/Al = 12 - 620) catalysts containing iron originally in the framework, in cationic sites and as oxide-like supported Fe species. All the catalysts exhibited very low activity in oxidation of propane by molecular oxygen, whereas in the propane reaction with nitrous oxide the propene yield was up to 20 %, besides formation of other oxygenates. The results of UV-Vis and EPR spectroscopy and reaction kinetic tests enabled to suggest that very small part of the well-isolated Fe-species is extremely active in propane oxidation by nitrous oxide following the %22propane - propanol ? propene - propanal ? COx%22 reaction pathway.
