Preparation of Mo-S-based Catalysts for Methanthiol Synthesis from High H2S-containing Syngas
Abstract:
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.
