Total oxidation of carbon monoxide, VOC and reduction of NO2 with catalytic ceramic filter media

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 ethan...
