Thiolation behaviors of methanol catalyzed by bifunctional ZSM-5@t-ZrO<inf>2</inf> catalyst
2022, Catalysis TodayCitation Excerpt :Numerous studies have been done on the modification and preparation of these two kinds of catalysts, and fruitful results have been obtained [3–6,11–13]. In terms of catalytic mechanism, process conditions, and reaction kinetics [14–18], it is generally believed that methanol can produce methoxy groups through adsorption and dissociation at the acid sites, and then the methoxy groups react with the sulfhydryl groups (HS-) generated from the dissociation of H2S at the base sites to form methanethiol. In the catalyst, the acid sites are favorable for the methanol conversion and the formation of methylene sulfide byproduct, while the base sites are favorable for the dissociation and adsorption of H2S and the selective formation of methanethiol [19–29].
Investigation on the catalytic conversion of hydrogen sulfide to methyl mercaptan as a novel method for gas sweetening: Experimental and modeling approaches
2019, Journal of Natural Gas Science and EngineeringCitation Excerpt :They have reported that when initial methanol concentration is reduced and the H2S:CH3OH ratio is lower than the stoichiometric value, the selectivity to produce dimethyl sulfide increases on W/Al2O3 catalysts. Mashkin and coauthors (Mashkin, 1994; Mashkin et al., 1995) studied the kinetics of the interaction existed between methanol and H2S at atmospheric pressure in the presence of an alumina–potassium–tungsten catalyst. Moreover, it was about 2004 when Yermakova and Mashkina studied the kinetics of the reaction of methanol with hydrogen sulfide in the presence of K2WO4/Al2O3 catalyst (Yermakova and Mashkina, 2004).
Promoting effect of SiO <inf>2</inf> on the K <inf>2</inf>WO <inf>4</inf>/Al <inf>2</inf>O <inf>3</inf> catalysts for methanethiol synthesis from methanol and H <inf>2</inf>S
2012, Catalysis CommunicationsCitation Excerpt :Methanethiol is an important chemical raw material and organic synthesis intermediate, in particular, methionine, a widely used feed additive or medicine. To date, methanethiol can be produced by methanol hydrosulfurization over acid–basic catalysts [1–11] or direct synthesis from H2S-containing syngas [12–14]. At present, the synthesis of methanethiol from methanol and hydrogen sulfide is an effective process and more favorable for industrial production due to the high productivity.
