摘要：

The adsorption of H2S on H-ZSM5 and Na-ZSM5 was investigated by means of IR spectroscopy, temperature-programmed desorption, and gravimetry. The surface chemistry for equilibrium pressures of H2S from 10(-5) to 0.5 mbar was studied. H2S was found to be hydrogen bonded to the SiOHAl groups of H-ZSM5, oriented in two different positions toward the surface. On the alkali-metal-exchanged form of ZSM5, H2S adsorbed coordinatively on the alkali-metal cation via the sulfur atom.
