摘要： A method is disclosed for reducing the sulfur deposition in the absorber of a Stretford process. In the Stretford process, hydrogen sulfide is removed from a gas stream by contacting the gas stream in an absorber with a circulating aqueous solution to convert the hydrogen sulfide to elemental sulfur particles, passing the solution containing the sulfur particles to a reaction vessel where the conversion of hydrogen sulfide to sulfur is completed, passing the solution containing the sulfur particles to an oxidizer, oxidizing the solution containing the sulfur particles in the oxidizer to form a regenerated solution, separating the sulfur particles from the regenerated solution, and recirculating the solution to the absorber. The sulfur deposition in the absorber is reduced by adding about 300 ppm of a hydroxyquinone compound, such as 1-hydroxyanthraquinone (1-HAQ); 1,2-dihydroxyanthraquinone (1,2-DHAQ); 1,8-dihydroxyanthraquinone (1,8-DHAQ); 1,2-dihydroxyanthraquinone 3-monosulfonic acid (1,2-DHAMA); 1,2,5,8-tetrahydroxyanthraquinone (1,2,5,8-THAQ); 1,4,5,8-tetrahydroxyanthraquinone (1,4,5,8-THAQ); 5- hydroxy 1,4-naphthoquinone (5-HNQ); or a mixture thereof, to the absorber.

摘要： A method for recovering lithium from its molten amalgam by electrolysis of the amalgam in an electrolytic cell containing as a molten electrolyte a fused-salt consisting essentially of a mixture of two or more alkali metal halides, preferably alkali metal halides selected from lithium iodide, lithium chloride, potassium iodide and potassium chloride. A particularly suitable molten electrolyte is a fused-salt consisting essentially of a mixture of at least three components obtained by modifying an eutectic mixture of LiI-KI by the addition of a minor amount of one or more alkali metal halides. The lithium-amalgam fused-salt cell may be used in an electrolytic system for recovering lithium from an aqueous solution of a lithium compound, wherein electrolysis of the aqueous solution in an aqueous cell in the presence of a mercury cathode produces a lithium amalgam. The present method is particularly useful for the regeneration of lithium from the aqueous reaction products of a lithium-water-air battery.
