摘　　要：The interaction between the adsorbed methylamine(MA) and siliceous FAU zeolite with a perfect framework is investigated with XRD, 29 Si and 13 C MAS NMR and FTIR. As methylamine is loaded into the zeolite, the crystal structure of the zeolite changes. One peak splits to four peaks for the 29 Si MAS NMR spectrum, and the IR vibration of framework with a high resolution become simpler. The fact indicates that there is a strong interaction between adsorbed methylamine and Si—O framework of FAU zeolite, leading to high A T value of affinity index for methylamine on the zeolite. The order structure of MA/FAU associate is discussed as well.The interaction between the adsorbed methylamine(MA) and siliceous FAU zeolite with a perfect framework is investigated with XRD, 29 Si and 13 C MAS NMR and FTIR.
