The promotion of sulfur oxides on the selective catalytic reduction (SCR) of NO by hydrocarbons in the presence of a low concentration of sulfur oxides over Ag/Al 2O 3 has been investigated by a flow reaction test and in situ infrared spectroscopy. When the C 3H 6 (or C 10H 22) + NO + O 2 feed-flow...
