摘要：

The interaction of H2S, ethanethiol and thiophene with H-ZSM5 were studied in situ by means of quantitative FTIR spectroscopy and gravimetry. Hydrogen bonding through the sulfur atom to the SiOHAl groups of the zeolite was concluded to be the primary type of interaction. The larger size of the sulfur atoms induced adsorption structures not observed with the corresponding oxygen compounds. In the case of thiophene adsorption at coverages higher than one molecule per acid site, hydrogen bonding was accompanied by the breakdown of the aromatic ring promoted by the strong acidity of HZSM5.
