Abstract:
A method for removing sulfur- and nitrogen-containing compounds from a liquid fuel that includes, hydrocarbon fuel compounds, comprising the steps of:a) oxidizing a liquid fuel with an oxidant to form oxidized sulfur- and nitrogen-containing compounds;b) monitoring the oxidizing of said liquid fuel;c) stopping said oxidizing when greater than about 90 percent of the sulfur- and nitrogen-containing compounds have been oxidized, but before any of the hydrocarbon fuel compounds have been oxidized;d) separating the liquid fuel containing oxidized sulfur- and nitrogen-containing compounds from depleted oxidant; ande) extracting said oxidized sulfur- and nitrogen-containing compounds from the liquid fuel by contacting said liquid fuel with a solvent that is selective for the oxidized sulfur- and nitrogen-containing compounds.
