cze Strukturní změny v FeMFI během jeho aktivace pro přímou amoxidaci propanu Různé charakterizační techniky, jako UV-VIS, FTIR, EPR a XPS, byly použity pro stanovení strukturních změn v Fe-silikátech s nízkou koncentrací železa, které byly aktivovány použitím odlišných metod (pomocí konvenční kydrotermální úpravy při 600 stupních C a pomocí zpracování ve zředěném toku amoniaku a propanu v heliu při 540 stupních C). Aktivované Fe-silikáty byly následně použity jako katalyzátory pro přímou amoxidaci propanu. n2o rozklad; struktura aktivních poloh; fe-mfi katalyzátory; oxidy dusíku; selektivní oxidace; fe-zsm-5 katalyzátory; paramagnetická rezonance; mossbauerova spektroskopie; benzen hydroxylace; bronstedova kyselost
eng Structural changes in FeMFI during its activation for the direct ammoxidation of propane Various characterization techniques, including UV-Vis, FTIR, EPR and XPS, were used for the description of structural changes in Fe-silicalite with low concentration of iron, which was activated using different methods (by conventional hydrothermal pretreatment at 600 degrees C and by treatment in the diluted flow of ammonia and propane in helium at 540 degrees C). Activated Fe-silicalite was subsequently used as a catalyst for the direct ammoxidation of propane. It has been shown that the studied methods of activation lead to materials with different catalytic behavior (activation in the flow of ammonia and propane resulting in the more active and selective catalytic materials). Results from the catalytic test are further discussed together with the results from the characterization of activated samples. direct n2o decomposition; active-site structure; fe-mfi catalysts; nitrous-oxide; selective oxidation; fe-zsm-5 catalysts; paramagnetic-resonance; mossbauer-spectroscopy; benzene hydroxylation; bronsted acidity
