    Abstract: Provided is a particulate filtration apparatus for removing combustible and noncombustible particulate matter from a lean burn engine exhaust gas stream containing particulate matter. The apparatus comprises a cyclone body with a roughened surface on the inner walls designed to trap and agglomerate the combustible particulate matter. A catalyst, selected from a selective catalytic reduction catalyst, an ammonia oxidation catalyst, a hydrolysis catalyst, an oxidation catalyst, a three-way catalyst, and combinations thereof can be coated on the roughened surface. Also provided is a system and methods for treating an exhaust gas stream.
