Processes for removing carbon disulfide from product streams containing a sulfide compound are performed by contacting the product stream with an alkanolamine and converting the carbon disulfide to a higher boiling point product, thereby reducing or eliminating carbon disulfide from the product stream. Subsequent removal of the higher boiling point product via distillation can lead to a purified sulfide stream with high purity.

Processes for removing carbon disulfide from symmetrical and asymmetrical sulfide product streams

The present disclosure provides for processes and systems for the purification of alkyl sulfide product streams including dimethyl sulfide (DMS). In some aspects, the disclosure provides for the removal of carbon disulfide (CS) from DMS via hydrolytic catalysis. In further embodiments, the disclosed catalytic processes are performed using mixed-metal catalyst systems such as cobalt-molybdenum (CoMo) and nickel-molybdenum (NiMo) catalyst systems.

Catalytic processes and systems for alkyl sulfide purification

Methods for synthesizing a mercaptan compound include the steps of contacting a nickel-molybdenum catalyst with HS at a sulfiding temperature of less than or equal to 235° C. to form a supported sulfur-containing catalyst, and then contacting an alcohol compound or an olefin compound, HS, and the supported sulfur-containing catalyst to form a reaction mixture containing the mercaptan compound.
