method for removing a sulfur-containing compound from a fuel stream of an internal combustion engine, removal fuel filter, and system for extending time between regeneration cycles of an emission control device

摘要

METHOD FOR REMOVAL OF A COMPOUND CONTAINING SULFUR FROM A FUEL CURRENT FROM AN INTERNAL FUEL ENGINE, FUEL FILTER FOR REMOVAL, AND SYSTEM TO EXTEND TIME PERIODS BETWEEN CONTROL CYCLES OF A DEVICE CONTROL DEVICE for removing sulfur-containing compounds from an internal combustion fuel stream. In one embodiment, the fuel filter comprises at least one column comprising an absorbent. In an exemplary embodiment the adsorbent is capable of removing sulfur-containing compounds, particularly sulfur-containing aromatic compounds, from fuel used in internal combustion engines, particularly diesel-type fuel. Also disclosed is apparatus for extending the life cycle of a post-combustion emission control device. In an 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 an 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 that part through the engine. for an emission control device.
