Abstract:
1. A method for treating emissions, the method comprising: charging carbon particles in an exhaust stream in a housing with a passage having an inlet and an outlet by a first corona discharge in a first chamber which generates a non-thermal plasma that charges the carbon particles with ions from the first corona discharge; producing one or more radicals by exciting gas atoms in the exhaust stream by the first corona discharge; oxidizing a portion of the charged carbon particles with a portion of the produced radicals to remove a portion of the carbon particles in the exhaust stream; attracting a portion of the charged carbon particles in the exhaust stream on a flow-through maintenance-free attraction system comprising a substrate core having a plurality of individual passages that extend therethrough and which fills a space in the housing passage that electrostatically attracts a portion of the charged carbon particles on a catalyzed attraction surface oppositely charged from the charged carbon particles and grounded; and oxidizing the attracted particles with another portion of the one or more produced radicals to self regenerate the at least one attraction surface.
