Abstract: By means of temperature-programmed desorption-mass spectroscopy(TPD-MS), infrared spectroscopy (IR).Mossbauer spectroscopy (MBS), methanol (CH₃OH) adsorption on Si-Fe zeolite was studied. It was found that CH₃OH can be adsorpted not only on Br(φ)sted acidic centres, but also on the surface basic centres. The acidic sites were cooperated with the basic sites in methanol adsorption. However, CH₃OH did not be adsorpted by Fe atoms. Amodel of methanol adsorption on the Si-Fe zeolite was proposed in this paper.

Key words: Si-Fe zeolite, Methanol adsorption
