  • Apparatus and Method for Storing and Releasing Sulfur Containing Aromatic Compounds From a Fuel Stream of an Internal Combustion Engine
    Publication number: 20110210051
    Abstract: Disclosed is a fuel filter for removing sulfur containing compounds from an internal combustion fuel stream. In one embodiment, the fuel filter comprises at least one column comprising an adsorbent. In one exemplary embodiment the adsorbent is capable of removing sulfur containing compounds, especially sulfur containing aromatic compounds, from fuels used in internal combustion engines, especially diesel fuels. Also disclosed is an apparatus for extending the life cycle of a post combustion emission control device. In one exemplary embodiment, the apparatus comprises a fuel filter for removing sulfur containing compounds from an internal combustion fuel stream and an emission control device. Finally, a method for removing sulfur containing compounds from an internal combustion fuel stream is disclosed.
