Studies on initiating agents for NaY zeolite and their characterization
【摘要】 综述了NaY沸石的常规溶胶导向剂、高温长效溶胶导向剂、高铝溶胶导向剂、改性溶胶导向剂以及凝胶导向剂的性能和研究现状,并对其现有表征手段如分光光度计、UV拉曼、液相29Si-NMR、液相27Al-NMR、固相23Na-NMR、电子衍射技术和硅钼黄动力学的特点进行了比较。
【Abstract】 The properties of and latest studies on initiating agents for NaY zeolites,including conventional sol initiating agents,high-temperature long-effect sol initiating agents,high-alumina sol initiating agents, modified sol initiating agents and gel initiating agents,were reviewed.The means for characterization of the initiating agents,e.g.,spectrophotometer,UV Raman,liquid phase 29Si-NMR,liquid phase 27Al-NMR, solid phase 23Na-NMR,electron diffraction and silicon-molybdenum kinetics,were compared.
