Abstract
An emissions control system for the after treatment of a fuel combustion process exhaust stream includes an exhaust passageway. The exhaust passageway allows for passage of an exhaust stream containing exhaust byproducts from the combustion of a fuel that includes a manganese compound. The exhaust stream includes a manganese compound which complexes with at least one of the exhaust byproducts.
Claims54
An emissions control system including the treatment of a diesel fuel combustion process exhaust stream, comprising:
- an exhaust passageway,
- an exhaust stream in the exhaust passageway, the exhaust stream containing exhaust byproducts from the combustion of a diesel fuel and also comprising a manganese compound comprising about 1 to about 30 mg Mn/liter of fuel,
- a catalyzed diesel particulate filter located within the exhaust passageway, the catalyzed diesel particulate filter contacting the exhaust stream, the exhaust stream comprising the manganese compound, the manganese compound complexing with at least one of the exhaust byproducts in the exhaust stream, the operation of the catalyzed diesel particulate filter enhanced by the manganese compound complexing with at least one of the exhaust byproducts in the exhaust stream, and
- the exhaust stream being free of a platinum group metal selected from the group consisting of platinum, palladium, rhodium, ruthenium, osmium, and iridium.
