A fuel filter for removing fuel impurities, particularly thiophenes, includes
a
hollow housing having a filter element therein. The filter element includes a substrate,
which may include a nonwoven fiber web, a plurality of particles, or both of these.
Where particles are used, the substrate may be homogeneous or may be a mixture
of different particles. The substrate may include a sorbent selected from the group
consisting of metals, metal oxides, metallic salts, organometallic compounds, catalysts,
and oxidizing agents. Optionally, a sulfur-treating reactant may be operatively
associated with the substrate to reduce the concentration of thiophenes in fuel
passing through the filter.
