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.

Claims (20)

1. An emissions control system for the after treatment of a diesel fuel combustion process exhaust stream, comprising:

an exhaust passageway for the passage of an exhaust stream containing exhaust byproducts from the combustion of a diesel fuel comprising a manganese compound,

a catalyzed diesel particulate filter located within the exhaust passageway and adapted to contact the exhaust stream,

wherein the exhaust stream comprises a manganese compound which complexes with at least one of the exhaust byproducts, whereby the operation of the catalyzed diesel particulate filter is enhanced, and wherein the manganese compound is an inorganic manganese compound.

2. An emissions control system as described in claim 1 , wherein the inorganic manganese compound is selected from the group consisting of fluorides, chlorides, bromides, iodides, oxides, nitrates, sulfates, phosphates, nitrides, hydrides, hydroxides, carbonates and mixtures thereof.

3. An emissions control system for the after treatment of a diesel fuel combustion process exhaust stream, comprising:

an exhaust passageway for the passage of an exhaust stream containing exhaust byproducts from the combustion of a diesel fuel comprising a manganese compound,

a continuously regenerating technology diesel particulate filter located within the exhaust passageway and adapted to contact the exhaust stream,

wherein the exhaust stream comprises a manganese compound which complexes with at least one of the exhaust byproducts, whereby the operation of the continuously regenerating technology diesel particulate filter is enhanced, and wherein the manganese compound is an inorganic manganese compound.

4. An emissions control system as described in claim 3 , wherein the inorganic manganese compound is selected from the group consisting of fluorides, chlorides, bromides, iodides, oxides, nitrates, sulfates, phosphates, nitrides, hydrides, hydroxides, carbonates and mixtures thereof.

5. An emissions control system for the after treatment of a diesel fuel combustion process exhaust stream comprising:

an exhaust passageway for the passage of an exhaust stream containing exhaust byproducts from the combustion of a diesel fuel,

a catalyzed diesel particulate filter located within the exhaust passageway and adapted to contact the exhaust stream,

wherein the exhaust stream has an additive introduced into it, the additive comprising a manganese compound which complexes with at least one of the exhaust byproducts, whereby the operation of the catalyzed diesel particulate filter is enhanced, and wherein the manganese compound is an inorganic manganese compound.

6. An emissions control system as described in claim 5 , wherein the inorganic manganese compound is selected from the group consisting of fluorides, chlorides, bromides, iodides, oxides, nitrates, sulfates, phosphates, nitrides, hydrides, hydroxides, carbonates and mixtures thereof.

7. An emissions control system for the after treatment of a diesel fuel combustion process exhaust stream comprising:

an exhaust passageway for the passage of an exhaust stream containing exhaust byproducts from the combustion of a diesel fuel,

a continuously regenerating technology diesel particulate filter located within the exhaust passageway and adapted to contact the exhaust stream,

wherein the exhaust stream has an additive introduced into it, the additive comprising a manganese compound which complexes with at least one of the exhaust byproducts, whereby the operation of the continuously regenerated technology diesel particulate filter is enhanced, and wherein the manganese compound is an inorganic metal compound.

8. An emissions control system as described in claim 7 , wherein the inorganic manganese compound is selected from the group consisting of fluorides, chlorides, bromides, iodides, oxides, nitrates, sulfates, phosphates, nitrides, hydrides, hydroxides, carbonates and mixtures thereof.
