Sulfur-containing carbonaceous materials are desulfurized by reaction with a mixture of an oxidizing agent and an oxygenated solvent such as diethyl ethe r under alkaline conditions at a temperature preferably ranging from ambient temperature to about 250 ~F (121 ~C) and a preferred pressure of about 1 atmosphere to 2 atmospheres. The use of radiation - such as X-ray, infrared, visible, microwave, or ultraviolet radiation, alpha, beta, or gamma radiatio n, other atomic radiation emanating from a radioactive material, or ultrasound - facilitates desulfurization. The products of the reaction are a desulfurized carbonaceous material in which the sulfur content is (for example) less than about 1 % and separated sulfur compounds.
