摘要/Abstract

摘要： 用高温气-固相置换法对ZK-4、NaA和NaHS3种沸石进行铝化。组成分析、尾气分析、X射线衍射、晶体形貌分析、红外光谱和²⁹Si高分辨魔角固体核磁结果表明,3种低硅铝比沸石铝化后骨架可能存在Al—O—Al键。

关键词: 铝化, Lowenstein规则, 气-固相置换反应

Abstract: Alumination of ZK-4, sodalite and NaAzeolites was carried out by gas-solid replacement reaction at a high temperature. Chemical analysis, effluent gas analysis, XRD, IR, SEMand ²⁹Si magic angle spinning NMRshowed that the Al-O-Al linkage is likely present in the framework of aluminated-ZK-4, aluminated-sodalite and aluminated-NaAzeolites after the three kinds of zeolites were aluminated at a elevated temperature.

Key words: Alumination, Lowenstein's law, Gas-solid replacement reaction
