Abstract EN
A series of Pt-Ce-Ba/γ-Al2O3 and Mn-Ce/γ-Al2O3 catalysts were synthesized by a sol-gel method and the samples were characterized by XRD, SEM, and EDS.
The effect of Mn-Ce/γ-Al2O3 on the storage and reduction of NO x over Pt-Ce-Ba/γ-Al2O3 catalysts was studied in a fix-bed reactor with simulation gases NO, O2, and N2.
The results indicated that NO oxidation to NO2 was reduced with the increase of inlet NO concentration, which was up to 83% when the concentration of NO was 500 ppm but reduced to 76% with the concentration of NO increasing to 1000 ppm.
Comparing with the Pt-Ce-Ba/γ-Al2O3 catalysts, the rate of NO x storage and reduction was remarkably increased over Pt-Ce-Ba/γ-Al2O3 combined with Mn-Ce/γ-Al2O3 catalysts.
However, the reductant used for NO x reduction reaction over Pt-Ce-Ba/γ-Al2O3 catalysts was consumed under the treatment of Mn-Ce/γ-Al2O3 catalyst, which caused the NO x conversion to obviously drop, but the rate of NO x absorption declined slightly.
