Abstract
Fossil fuels are combined with a hydroperoxide in an aqueous-organic medium and subjected to ultrasound, with the effect of oxidizing the sulfur compounds in the fuels to sulfones. Due to their high polarity, the sulfones thus formed are readily removed from the fuels by polar extraction. The process is thus highly effective in removing sulfur compounds from the fuels.
