本文主要采用~(129)Xe-NMR,并结合~(29)Si-与~(27)Al-NMR技术,探讨了在ZSM-5沸石上引入的锌及NaY沸石上引入的稀土阳离子的存在状况,高温焙烧过程对HZSM-5骨架结构的影响。
In this paper, the presence of rare earth cations introduced on zinc and NaY zeolites introduced onto ZSM-5 zeolites was investigated by ~ (129) Xe-NMR and ~ (29) Si- and ~ (27) Effect of High-temperature Roasting Process on HZSM-5 Skeleton Structure.
