Catalytic N 2O decomposition on Pr 0.8Ba 0.2MnO 3 type perovskite catalyst for industrial emission control
Original language description
Ba substituted PrMnO 3 type perovskite catalysts (Pr 1-x Ba x MnO 3 with x = 0.1-0.4) have been studied for N 2O decomposition reaction. These catalysts were prepared by a combination of co-precipitation and impregnation methods. They are characterized in detail by means of XRD, BET-SA, SEM, EDX, O 2-TPD, H 2-TPR and XPS analysis. The catalytic activity of Ba substituted PrMnO 3 catalyst was observed to be relatively better than the bare catalyst, thereby showing the promotional effect of barium, and Pr0.8Ba 0.2MnO 3 with 20 mol% substitution was found to be the optimized composition. The Pr 0.8Ba 0.2MnO 3 catalyst composition was also prepared in supported form using ceramic honeycomb by following in situ co-precipitation method and tested for N 2O decomposition reaction under simulated feed conditions. Supported catalyst shows 92% conversion of N 2O at 550 °C with a maximum of 0.0984 mmol of N 2O decomposed per gram of the catalyst, per unit time in the presence of NO and O 2, which
