 Abstract: The reaction of ethanol with hydrogen sulfide was studied on divalent cation-exchanged X-type zeolites at 523 K. The decomposition of ethanol to hydrocarbons is competitive with the hydrosulfurization process, i.e., the reaction between EtOH and H2S. Brönsted acid sites together with divalent cations are involved in the hydrosulfurization of ethanol. Cation sites take part in the formation of ethanethiol. The increase of the strength of Brönsted acid sites causes the increase of the selectivity towards diethyl sulfide.
