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: 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: A system of reforming reactors comprises a plurality of reactors coupled by flow lines, a feed header coupled to the plurality of reactors by a plurality of feed lines, an effluent header coupled to the plurality of reactors by a plurality of effluent lines, and a plurality of valves disposed in the flow lines, the feed lines, and the effluent lines. Each reactor comprises a reforming catalyst, and the plurality of valves is configured to dynamically connect the plurality of reactors to create a first serial flow path and reconnect the plurality of reactors to create a second serial flow path through the plurality of reactors. A first reactor of the plurality of reactors is adjacent to a second reactor of the plurality of reactors in the first serial flow path, and the first reactor is not adjacent to the second reactor in the second serial flow path.
