Title: Relation between chemisorption and catalytic transformation of R{sub 2}S compounds on faujasite-type zeolites

Abstract

The adsorption and transformation of sulfur organic compounds on faujasite-type zeolites are considered using ethanethiol and diethyl sulfide molecules as examples. Alkali-metal-exchanged and -protonated forms of the zeolites presenting various nature and various strength of the active centers were applied. The difference in thiol and sulfide chemisorption on MNaY zeolites (M = Li, K, Rb, Cs) relies on the formation of the hydrogen bond between ethanethiol and the basic sites of zeolites together with the coordination bond which occurs for both thiol and sulfide. That implicates the high activity of MNaY zeolites in the decomposition of ethanethiol. Protonated forms of zeolites are highly active in the transformation of diethyl sulfide to ethene and ethanethiol thanks to the formation of hydrogen bonding species followed by the protonation of the sulfide molecule.
