Title
Disparate effects of SO2 on the selective catalytic reduction of NO by C2H5OH and IPA over Ag/Al2O3
Abstract

The selective catalytic reduction (SCR) of NO by C2H5OH and IPA (isopropyl alcohol) over Ag/Al2O3 was studied in the presence of SO2. The results showed that C2H5OH performs much more effectively in the presence of SO2 compared with IPA. In situ DRIFTS study did not show the formation of sulfate species on Ag/Al2O3, which might explain the high resistance of Ag/Al2O3 to SO2 in the SCR of NO by C2H5OH. In addition, the deactivation mechanism for the case using IPA as a reductant was also proposed based on the IR spectra results.
