Abstract
Tellurium used as promoter was investigated in the preparation of K2MoO4/SiO2 catalyst for methanethiol synthesis from high H2S-containing syngas. The experimental results showed that the addition of Te to K2MoO4/SiO2 improved the activity of catalysts and the selectivity of methanethiol. ESR results reveal that the addition of Te decreases the content of "oxo-Mo5+" species and increase that of the "oxysulfo-Mo5+" species, simultaneously increase the low valence states of sulfur species. XPS results reveal that the addition of Te to K2MoO4/SiO2 increase the amount of low valence states of molybdenum and sulfur species, which are related to the formation of methanethiol.
