Abstract (en)
The invention pertains to a regenerative soot filter (1) device applicable to exhaust gases from combustion engines, particularly diesel type engines. The device comprises a microwave generator (16) and a soot filter material (10), wherein a microwave absorbing material is provided on the soot filter material. The invention also pertains to a method of regenerating a soot filter comprising soot filter material applicable to exhaust gases from combustion engines, particularly diesel type engines. The method comprises applying microwave radiation to the soot filter by a microwave generator and passing a gas flow comprising oxygen over the soot filter, wherein the microwave radiation applied to the soot filter is absorbed by a microwave absorbing material that is provided on the soot filter material. <IMAGE>
