Adsorption-desorption behavior and mechanism of dimethyl disulfide in liquid hydrocarbon streams on modified Y zeolites

- Effect of the surface acidity on adsorption of DMDS has been studied.
- Vibrations of ν(C-S), ν(S-S) and ν(Cu-S) were measured with the Raman spectrum.
- XPS results indicated the autoreduction of Cu2+ to Cu+ on Cu-Y zeolite.
- FTIR and DMDS-TPD results indicated adsorption mechanisms on Cu(I)-Y zeolite.
- Activated energy of desorption (EA) was obtained through the DMDS-TPD results.
