A process for removing soot from the exhaust gas of a diesel engine by oxidizing the nitrogen monoxide present in the exhaust gas to nitrogen dioxide, separating the soot from the exhaust gas stream and oxidizing the soot using the nitrogen dioxide produced. The process is performed in at least two consecutive process stages and the soot is separated from the exhaust gas stream with an efficiency W between 0.05 and 0.95 in each process stage, wherein each process stage can be assigned a transmission for soot in accordance with T=1-W and the total transmission of the process for soot is given as the product of the transmissions of all the process stages.
