Abstract: The interaction between the adsorbed methylamine(MA) and siliceous FAUzeolite with a perfect framework is investigated with XRD, 29Si and 13C MAS NMRand FTIR. As methylamine is loaded into the zeolite, the crystal structure of the zeolite changes. One peak splits to four peaks for the 29Si MAS NMRspectrum, and the IRvibration of framework with a high resolution become simpler. The fact indicates that there is a strong interaction between adsorbed methylamine and Si—Oframework of FAUzeolite, leading to high A Tvalue of affinity index for methylamine on the zeolite. The order structure of MA/FAUassociate is discussed as well.
