ABSTRACT:
System and method for supplying reductants to an emission treatment system. The system includes a fuel tank adapted to supply a premixed fuel stream that includes a primary component and a reductant component, and an engine in fluid communication with the fuel tank, wherein the engine is configured to create an emission. The engine includes an emission treatment system to treat the emission. The system also includes a separation system that includes a membrane with differential permeability for the reductant component relative to the primary component. The separation system is configured to receive at least a portion of the premixed fuel stream from the tank and to separate the premixed fuel stream into a first fraction and a second fraction. The first fraction includes a higher concentration of the reductant component than the second fraction, and the separation system is configured to supply the first fraction to the emission treatment system.
