Abstract
A system is provided for supplying reductants to an emission treatment unit. 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 an oxygenate reductant component. An engine is in fluid communication with the fuel tank, wherein the engine is configured to receive the first premixed fuel stream and create an exhaust stream. The system further includes an emission treatment unit to treat the exhaust stream. A separation unit is configured to receive the second premixed fuel stream, separate the second premixed fuel stream into a first fraction stream and a second fraction stream, and supply the first fraction stream to the emission treatment unit, wherein the first fraction stream comprises a higher concentration of the oxygenate reductant component than the second fraction stream.
