ABSTRACT:
The sulfur content of solid carbonaceous material, such as coal or lignite, is reduced by feeding said material under recycle gas pressure into a continuous closed pressurized cyclic system operating in the range of about 5 to 30 atmospheres, contacting the coal in a desulfurization zone of the cyclic system with hot hydrogen-containing gases at about 1600.degree. F, removing the desulfurized coal from the resulting gas stream, removing sulfur compounds from the gas stream, and burning a part of the resulting gas stream to supply the hot hydrogen-containing gases for contacting the coal. Hydrogen necessary for the recycle gas stream is generated from the coal in the desulfurization zone. The only input to the system is coal and oxygen. Desulfurized coal, sulfur and excess gases are removed as products.
