Oxidative desulfurization (ODS) is a process used to remove sulfur compounds from fuels, primarily diesel and gasoline. This process involves the oxidation of sulfur-containing compounds to form sulfoxides or sulfones, which are then more easily removed by extraction or adsorption techniques. The removal of sulfur is crucial as sulfur compounds can lead to the formation of sulfur dioxide (SOâ) upon combustion, which contributes to environmental pollution and acid rain. Moreover, sulfur can poison catalytic converters used in vehicles, reducing their efficiency.
