Filter apparatus for removing sulfur-containing compounds from liquid fuels, and methods of using same

A liquid fuel filter for removing sulfur-containing compounds from a liquid fuel, comprising:

• a thin-walled hollow housing body defining a chamber therein;
• an inlet connected to the housing body and in fluid communication with the chamber thereof;
• an outlet connected to the housing body and in fluid communication with the chamber thereof;
• a liquid fuel filter media disposed in the housing chamber for filtering liquid fuel and for removing sulfur-containing compounds therefrom;
• the liquid fuel filter media comprising:
• a plurality of substrate particles;
• and
• a reagent operatively associated with a plurality of particles selected from said substrate particles, said reagent being capable of reacting with thiophenes.
