The synthesis of methyl mercaptan was investigated in a two-step process. That is, production of COS from H₂S containing synthesis gas and subsequent hydrogenation over supported MoS₂ based catalysts. In the reaction network, CS₂ was identified as direct precursor of methyl mercaptan. Potassium led to significant improvements in the yield of methyl mercaptan. Two catalytically active phases (pure MoS₂ and K decorated MoS₂) were evidenced by combining kinetic measurements and physicochemical characterization of the catalysts. Cobalt and potassium promotion led to an increase in the rates of all reactions within the reaction network.     «
