NO oxidation over Pt based catalysts for Hybrid fast SCR process |
| 초록 |
Different catalysts containing platinum were studied for the oxidation of NO with various concentrations of oxygen, nitrogen monoxide and nitrogen dioxide. The order of activity for oxidation reaction was found to be: Pt/WO3/TiO2 anatase > Pt/TiO2 rutile > Pt/Al2O3. Moreover anatase and rutile has same chemistry i.e. TiO2 but different structure. The conversion of NO to NO2 increases with increasing oxygen concentration from 3 to 10%, but it levels off at higher concentrations. The conversion to NO2 decreases with increasing feed concentrations of NO and also decreases by the addition of NO2 to the feed. Both these observations suggest that the oxidation of NO on Pt based catalysts is autoinhibited by the reaction product NO2. Further experiments were performed for the oxidation of SO2 and its effects on NO oxidation. NO conversion was slightly decreased by the effect of SO2 over anatase catalysts but highly affected by SO2 over rutile catalyst. On the other hand, the presence of NO showed remarkbly high conversion of SO2 over all catalysts. |
