Abstract

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 WO 3/ZrO 2, La 2O 3/Al 2O 3, Al 2O 3, and HZSM-5 catalysts were active and selective in the production of dimethyl sulfide. The WO 3/Al 2O 3 catalyst was less active than these four, but was selective to methanethiol. Based on this work and results in the literature, a mechanism was proposed that correlates methanethiol selectivity to catalyst acid strength.
