Abstract: A process for converting carbon disulfide (CS₂) to hydrogen sulfide (H₂S) in mixtures of H₂S and CS₂ is provided. The H₂S/CS₂ mixture is combined with water to form a hydrolysis feed mixture. The hydrolysis feed mixture is passed through a hydrolysis reactor containing e.g., an alumina-based catalyst, wherein a substantial portion of the CS₂ is converted to additional H₂S. A vapor product comprising H₂S, CO₂, unreacted H₂O, unconverted CS₂ and sulfur is formed by the hydrolysis reaction. The vapor product is cooled to form a H₂S/CO₂ vapor phase and a sour water condensate phase. The H₂S/CO₂ vapor phase is separated from the sour water condensate phase and subsequently recovered. The sour water condensate phase, which contains small amounts of solid sulfur particles, is optionally then combined with additional CS₂ and decanted to form a sulfur-free sour water layer and a CS₂ layer containing dissolved sulfur. The sour water layer is recycled and combined with the original H₂S/CS₂ mixture. The CS₂ layer is recycled to a sulfur removal device to remove the sulfur dissolved in the CS₂.
