Abstract
Provided are methods of reducing a sulfur concentration in a liquid fuel and methods of forming a thiophene/metal complex in a liquid fuel. The method can involve combining a liquid fuel and at least one metal acetate to form a thiophene/metal complex and substantially removing the thiophene/metal complexes from the liquid fuel. A thiophene concentration in a liquid fuel is reduced by the formation of an insoluble complex salt, which can be removed by, for example, centrifuge, filtration, decantation, and/or distillation.
