| Abstract: | Methyl mercaptan is an important chemical commodity widely used in the production of pesticides, pharmaceuticals, petrochemicals and for material synthesis. The main application of CH3SH lies in the production of methionine, while an amino acid was used as an animal feed supplement. The production of Methanethiol from one-step reaction of syngas and hydrogen sulfide has been a hot area of research due to its characteristics of ready availability of reactant and simple process. This review has summarized the research progress of Mo-based, tungsten-based and vanadia-based catalysts for Methanethiol Synthesis from High-H2S Containing Syngas, especially the effects of promoter and supporter on Mo-based catalyst. The reaction pathway and mechanism for the synthesis of methyl mercaptan have been explored. Lastly, the application prospect of this reaction has been predicted. |
