摘要： 本文用程序升温脱附-质谱联合、红外光谱、穆斯堡尔谱等手段研究了甲醇在丝光型Si-Fe沸石上的吸附过程并探讨了吸附机理。研究结果表明,甲醇不仅可能吸附在沸石的酸中心上,也可能吸附在沸石的碱中心上。酸碱中心在甲醇吸附时起着一定的协同作用。文中给出了吸附模型。

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.
