Oxidation of Perchloroethylene?Activity and Selectivity of Pt, Pd, Rh, and V2O5 Catalysts Supported on Al2O3, Al2O3?TiO2 and Al2O3?CeO2. Part 2
Original language description
The H2-TPR experiments proved that the enhanced reducibility is the key feature of the catalyst in PCE oxidation: both the activity and the selectivity followed the orders of catalysts? reducibility. The NH3-TPD measurements showed that the acidity is not the determining property of the catalyst in the PCE oxidation. After the 40.5 h stability test, no carbonaceous species were seen on the Pt/Al2O3?CeO2 catalyst?s surface. During the oxidation strong correlation between the water concentration in the feed and the HCl yield was seen. In the absence of oxygen, i.e. during destructive adsorption, the presence of water had even more pronounced effect on the HCl formation and on the catalysts? stability. The oxidation of PCE over the Pt/Al2O3 and Pt/Al2O3?CeO2 catalysts and in the presence of excess hydrogen proceeds via detaching the chlorine atoms before the breakage of the carbon?carbon double bond, and hence following the order of the lowest bond energy in each step.
