Název v původním jazyce

Cu-ZSM-5 zeolite highly active in reduction of NO with decane under water vapor presence - Comparison of decane, propane and propene by in situ FTIR

Popis výsledku v původním jazyce

Selective catalytic reduction of NOx (SCR-NOx) with decane, and for comparison with propane and propene over Cu-ZSM-5 zeolite (Cu/ Al 0,49, Si/Al 13.2) was investigated under presence and absence of water vapor. Decane behaves in SCR-NOx like propene, i.e. the Cu-zeolite activity increased under increasing concentration of water vapor, as demonstrated by a shift of the NOx-N-2 conversion to lower temperatures, in contrast to propane, where the NOx-N-2 Conversion is highly suppressed. In situ FTIR spectra of sorbed intermediates revealed similar spectral features for C10H22- and C3H6-SCR-NOx, where -CHx, R-NO2, -NO3-, Cu+-CO, -CN, -NCO and -NH species were found. On contrary, with propane -CHx, R-NO2, NO3-, Cu+-CO represented prevailing species. A comparison of the in situ FTIR spectra (T-O-T and intermediate vibrations) recorded at pulses of propene and propane, moreover, under presence and absence of water vapor in the reaction mixture...
