  • Publication number: 20090173061
    Abstract: A system is provided for operating a diesel engine with reduced emissions of NOx. The system comprises a fuel tank adapted to directly or indirectly supply a first premixed fuel stream and a second premixed fuel stream, wherein each fuel stream comprises a primary fuel component and a reductant component. An engine is in fluid communication with the fuel tank, whereby the engine is configured to receive the first premixed fuel stream and create an exhaust stream. The system includes an emission treatment unit to treat the exhaust stream, and a separation unit configured to receive the second premixed fuel stream. The separation unit is also configured to separate the second premixed fuel stream into a first fraction stream and a second fraction stream, and supply the first fraction stream to the exhaust stream. The first fraction stream comprises a higher concentration of the reductant component than the second fraction stream.

  • Publication number: 20090173058
    Abstract: A system is provided for the on-board production of reductants. The system comprises a fuel tank adapted to directly or indirectly supply a first fuel stream and a second fuel stream. An engine is in fluid communication with the fuel tank, and is configured to receive the first fuel stream and create an exhaust stream. The system further includes an emission treatment unit to treat the exhaust stream. A fuel conversion unit is configured to receive the second fuel stream, and also receive a stream comprising oxygen to partially oxidize at least a portion of the second fuel stream thereby forming reductants. In addition, the fuel conversion unit is configured to supply a reductant stream comprising the reductants to the exhaust stream. The invention further provides a method for the on-board production of reductants including supplying a first fuel stream to an engine, wherein the engine is configured to create an exhaust stream.

  • Publication number: 20090139215
    Abstract: A method is provided for operating a diesel engine with reduced emissions. The method comprises combusting a first biodiesel blend fuel in a diesel engine resulting in the production of diesel exhaust gases containing NOx. The diesel exhaust gases are admixed with a second biodiesel blend fuel, and the second biodiesel blend fuel is hydrolyzed to form reducing agents. The diesel exhaust gases containing NOx are passed through an NOx-reducing catalyst to reduce the NOx through a selective catalytic reduction reaction with the reducing agents. The invention further provides a method for operating a diesel engine with reduced emissions, comprising combusting a first biodiesel blend fuel in a diesel engine resulting in the production of diesel exhaust gases containing NOx. A second biodiesel blend fuel is converted in a fuel processor thereby forming reducing agents, and the diesel exhaust gases are admixed with the reducing agents.

  • Patent number: 7494634
    Abstract: Systems and methods of removing at least nitrogen oxides from an exhaust fluid generally include dividing a flow of an exhaust fluid comprising a concentration of nitric oxide into three types of flow-through cells. The first flow-through cell comprises a catalyst configured to reduce the nitric oxide with a reductant to form a first feedstream comprising nitrogen containing species derived therefrom. The second flow-through cell comprises a catalyst configured to oxidize nitric oxide to form a second feedstream comprising nitrogen dioxide. The third flow-through cell does not change the nitric oxide concentration and form a third feedstream comprising nitric oxide. After flowing through the three different types of cells, the feedstreams are mixed to form a homogenous mixture and then fed to a catalyst bed configured to convert the nitrogen containing species, the nitric oxide, and the nitrogen dioxide to a fluid comprising nitrogen gas and water.
