Abstract in another language

The development of a SiC-carbide based filter that combines a low pressure drop due to a graded pore structure with high filtration performance ascribed to different filtration mechanism is presented. The processing route is based on carbon paper/carbon black composites with graded porosity. By microwave assisted chemical vapor infiltration (CVI) the composite is coated with silicon and partially carbidized in a way, that the oxidation resistivity of the obtained SiC is combined with the good mechanical strength of the remaining carbon fiber core. To reduce the soot removal temperature during operation, the material is coated with a Platinum/TiO2-catalyst.
