Abstract

The invention provides a process for removing soot particles from exhaust gas from produced by a diesel engine. The process uses a particle filter (1) that collects soot particles with the aid of nitrogen dioxide which is generated by catalytic oxidation of nitrogen monoxide contained in the exhaust gas. The process is characterized in that the particle filter (1) is a deep-bed particle filter, having a filtration efficiency for the soot particles. The particle filter is coated with a catalytic coating (2) for oxidizing nitrogen monoxide to nitrogen dioxide and the exhaust gas leaving the particle filter subsequently filtered through a particle filter serving as a soot barrier (3). The filter can have a filtration efficiency of over 95 %.
