Реферат:
Monolith washcoated catalysts with potential for diesel emission control have been developed. Two types of catalysts have been prepared for further study: (1) MnOx supported on granulated ?-Al2O3, (2) MnOx supported on cordierite monolith washcoated with ?-Al2O3. Both catalysts have been calcined at 500 and 900 �C and subsequently modified by doping with 0.1�1.0 wt% of Pt or Pd. The influence of the concentration of both manganese oxide (0�10 wt%) and noble metals Pt and Pd in the range 0�1.0 wt% on the catalytic activity in methane oxidation has been studied. Comparison of the catalytic activity of MnOx/Al2O3 and MnOx + Pt(Pd)/Al2O3 with that of a standard 1 wt%Pt/Al2O3 catalyst shows the existence of a synergetic effect. This effect is more pronounced for the samples calcined at 900 �C. The developed monolithic catalysts MnOx + Pt(Pd)/Al2O3 demonstrate higher activity and thermal stability (up to 900 �C) compared to the commercial monolithic catalyst (TWC's).
