Abstract

The invention relates to a method for removing soot particles from an exhaust gas stream of internal combustion engines in a module (1) by oxidation of the soot particles temporarily captured in a catalytic converter with nitrogen dioxide (NO 2 ), the nitrogen dioxide oxidizing the nitrogen monoxide (NO) present in the exhaust gas a catalyst (2) is formed as a function of the flow rate of the exhaust gas at a temperature above about 200 ° C. In this case, the exhaust gas is passed through at least two noble metal-coated open-pored metal foams (2), which increase a nitrogen dioxide concentration in the exhaust gas, and open-cell metal foams (3, 4) downstream of these.
