Abstract
A sour liquid hydrocarbon feedstock is desulfurized upon contact with a hydrogen gas in the presence of a catalyst to obtain a low sulfur product and a hydrogen sulfide gas by-product. The hydrogen sulfide gas is treated with an anthraquinone which is dissolved in a solvent having a polarity which is greater than 3 Debye units, to produce sulfur and oxygen. The oxygen is used to oxidize a hydrocarbon fuel and produce the hydrogen gas used in the initial desulfurization step.
