Abstract (englisch):
This paper deals with the effect of catalyst loading on the activity and selectivity of CuOx􀀀 MnOy catalysts on
alumina-silicate supports (fiber material-Al2O3(44)/SiO2(56)). A special focus lies on the oxidation of CO, on
mixtures of VOC from 1-butene, isobutane, n-butane, propane, ethene, and ethane, as well as on CO oxidation in
the presence of NO2. The catalysts are prepared through wet impregnation of the filter section with an aqueous
solution of copper and manganese nitrate. The rate of CO oxidation for small carbon monoxide concentrations of
up to 1 vol.% is independent of catalyst loading in the filter material. In contrast, at a carbon monoxide concentration
of around 3 vol.%, it is found that the rate of CO oxidation increased rapidly with increasing catalyst
loading of the filter material. The highest catalytic activity of over 93% CO elimination is achieved at 290 ◦C for
1 vol.% CO and smaller catalyst loading and for 3 vol.% CO with higher catalyst loading. In long-term stability
tests, complete CO conversion is measured without deactivating the catalyst at 390 ◦C for at least 100 h. The
highest catalytic activity for VOC elimination of 90% is achieved in the temperature range of 350–420 ◦C. ... mehr
