Selective catalytic reduction of NO by propylene over Ag/Al2O3, Pt/Al2O3, Ag/TiO2 and Pt/TiO2 catalysts

View through CrossRef
The selective catalytic reduction of nitric oxide with propylene in the presence of oxygen was studied over Ag/Al2O3, Pt/Al2O3, Ag/TiO2, and Pt/TiO2 catalyst were very active at lean NO reduction with the best reaction temperature at 450, 300, 400, and 250℃ respectively. The presence of water vapor decreased the activity of Pt/Al2O3 and Ag/TiO2 catalysts but increased the activity of Ag/Al2O3 and Pt/TiO2 catalysts. Since Ag/Al2O3 and Pt/Al2O3 catalyst had different effective temperature ranges therefore a two-stage catalyst in a reactor composing of Ag/Al2O3 catalyst followed by Pt/Al2O3 catalyst was tested for the activity. It was found that the activity was increased appreciably due to the broadened temperature window according to the sum of the temperature windows of the two catalysts.
