Catalytic sulfur degassing
A process is described for the preparation of (1) synthesis gas reduced in solids and acidic gases and (2) elemental sulfur which comprises (a) treating coal, shale or tar sands with oxygen to produce a synthesis gas stream containing inorganic sulfide; (b) recovering slag particles from the treatment of coal in step (a) and selecting particles thereof suitable for use as a catalyst carrier; (c) treating the slag from step (b) with the synthesis gas substantially free of slag particles to deposit on the surface slag particles a catalytic amount of at least one metal sulfide; (d) treating the synthesis gas from step (c) to remove acidic gases suitable for sulfur production; (e) converting the acid gases from step (d) to liquid sulfur; and (f) contacting the liquid sulfur with the catalytic slag particles from step (c) to reduce the hydrogen sulfide and hydrogen polysulfide content of the sulfur.
