| Abstract: | Pt / CeO2-ZrO2/Al2O3 catalysts coated on metallic substrate are produced by the method of impregnation and the catalytic oxidation activity on low concentration methane is determined. The result indicates that Pt / CeO2-ZrO2/Al2O3 catalytic metallic substrates have high catalytic activity. The higher Pt is loaded, the better the catalytic activity is. 7% Pt / CeO2-ZrO2/Al2O3 catalyst＇ T50 is 359℃anal the T90 iS 442℃, the space velocity is 15000h-1, and the methane removals reaches 92%. |
