Zeolite And Metal Oxide Catalysts For The Production Of Dimethyl Sulfide And Methanethiol, Craig Plaisance
Zeolite And Metal Oxide Catalysts For The Production Of Dimethyl Sulfide And Methanethiol, Craig Plaisance
LSU Master's Theses
Metal oxide and zeolite catalysts were examined to determine their suitability for the production of methanethiol and dimethyl sulfide from the condensation of methanol and hydrogen sulfide. Fixed bed reactor experiments were used to test the catalysts in these processes. The acid sites of these catalysts were characterized by investigating the thermal desorption of 1-propanamine from these sites. It was found that WO3/ZrO2, La2O3/Al2O3, g-Al2O3, and HZSM-5 catalysts were active and selective in the production of dimethyl sulfide. On these four catalysts, the reaction converting methanol to dimethyl ether and the methanethiol disproportionation reaction were fast and close to equilibrium. …
