Abstract: 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 (CS2) 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.

Abstract: 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.

Abstract: The present disclosure generally relates to processes to produce a mercaptan and an asymmetrical sulfide utilize stacked bed catalyst systems containing CoMo and NiMo, and these processes demonstrate a synergistic reduction in the amount of ethylene, methyl mercaptan, ethyl mercaptan, and H2S in product mixtures. In aspects, the conversion of limiting reactants in the synthesis of asymmetrical sulfides unexpectedly remain high under increased flow rates through the catalyst bed, and under reduced temperatures and pressures. In further aspects, reactor systems configured for the independent synthesis of mercaptans and asymmetrical sulfides in a single fixed bed catalyst vessel are also disclosed as a simplification of existing reactor systems employing separate reactors for separate mercaptan and sulfide syntheses.

Abstract: Methods for synthesizing a mercaptan compound include the steps of contacting a nickel-molybdenum catalyst with H2S 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, H2S, and the supported sulfur-containing catalyst to form a reaction mixture containing the mercaptan compound.

Abstract: Pyrrole compounds are produced by contacting a furan compound, a solid acid catalyst, and water to form a reaction mixture containing a ?-dicarbonyl compound, and then contacting the ?-dicarbonyl compound with ammonia or an ammonium salt to form a reaction product mixture containing the pyrrole compound. A representative pyrrole compound that can be synthesized using these processes is 2,5-dimethylpyrrole.
