The process and apparatus for reducing soot in soot-containing gases, such as exhaust gases from a Diesel engine, by applying thereto an alternating or pulsating voltage to promote oxidation of soot and to change the character of soot. The resultant gas may be contacted with active medium, such as a heated net of metal or an oxidation catalyst, to oxidize the remaining soot.
