Optimization of Cs content in Co-Mn-Al mixed oxide as catalyst for N2O decomposition
Original language description
The series of Co-Mn-Al mixed oxide catalysts with different amount of Cs (0.5?4.6 wt.%) was prepared by calcination of Co-Mn-Al hydrotalcite (Co:Mn:Al = 4:1:1) and followed by impregnation by cesium salt (CsNO3, Cs2CO3) using pore filling method. Chemical analysis, XRD, N2 sorption, TPR-H2, TPD-CO2 and TPD-NH3 were used to characterize the catalysts. All prepared catalysts were tested for N2O catalytic decomposition in inert gas and in the presence of oxygen, water vapor and nitric oxide. The influenceof Cs salts used for catalyst preparation, cesium amount and calcination temperature on catalysts activity and stability were studied. The catalytic activity increases with increasing amount of cesium promoter. The catalysts containing ca. 3.2 wt.% Cs was the most active one under the conditions simulating the composition of the waste gas (N2O, O2, H2O) upstream the SCR NOx unit in a nitric acid plant.
