Direct Ammoxidation of Propane over Zeolites with Traces of Iron
Original language description
The performance of Fe-zeolites in ammoxidation of propane at 540 degrees C in presence of molecular oxygen, nitrous oxide or their mixture has been investigated. The results presented here clearly show ability of Fe-silicalites to catalyze direct ammoxidation of propane. Ammoxidation of propane takes place on special extraframework Fe ions exclusively generated by hydrolysis of framework Si-O-Fe bonds. Introduction of Fe ions into silicalite matrix by post-synthesis modification does not lead to an active catalyst for propane ammoxidation. The presence of aluminum atoms in the framework is disadvantageous for propane ammoxidation, in contrast to propane oxidative dehydrogenation by nitrous oxide, due to decomposition of acrylonitrile on strong acidic sites.

Přímá amoxidace propanu na zeolitech se stopami železa
Czech description
Byla studována účinnost Fe-zeolitů v amoxidaci propanu při 540 °C v přítomnosti molekulárního kyslíku, oxidu dusného a jejich směsi. Výsledky jasně ukazují schopnost Fe-silikalitů katalyzovat přímou amoxidaci propanu. Tato reakce probíhá na mimomřížkových iontech železa generovaných výhradně hydrolýzou Si-O-Fe vazeb. Post-syntetické vnášení želůeza do silikalitu nevede k tvorbě aktivního katalyzátoru. Přítomnost hliníku v mřížce vede k rozkladu akrylonitrilu na acetonitril.
