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. In one exemplary embodiment, the method comprises passing a fuel through a fuel filter capable of removing sulfur containing compounds, storing the removed sulfur containing compounds, releasing a portion of the stored sulfur containing compounds, and sending the portion through the engine and into an emission control device.
