The catalytic performance of Mo-S-K-based catalysts prepared with different precursors for synthesis of methanthiol from high H₂S containing syngas has been investigated. The effects of the promotors K₂CO₃, KCl and KF on the activity of the catalyst under various temperature and pressure conditions have been examined. The results show that MoS₂/K₂CO₃/γ-Al₂O₃ catalyst prepared with precursor (NH₄)₂MoS₄ was found to have the same catalytic behavoir as that prepared from K₂MoS₄. XRD measurements indicate the existence of a new Mo-S-K phase (2θ=29.8° and 30.8°) in the catalyst both of MoS₂/K⁺/γ-Al₂O₃ promoted by weak basic potassium salts (K₂CO₃ and KF) and of K₂MoS₄/γ-Al₂O₃ respectively.
