沸石的化学组成、结构与色谱参数Vg值之间的变化规律

Study on The Variation Characteristic of The Chemical Composition And Structure of Zeolite to Chromatographic Parameter Value(Vg)

采用吸咐色谱法首次研究了Ｙ型沸石的结构，化学组成与吸附保留值（Ｖｇ）之间的变化规律．实验证明苯和正己烷的Ｖｇ值及其差值上△Ｖｇ都与Ｙ型沸石的物化参数硅铝比（Ｍ＝ＳｉＯ２／Ａｌ２Ｏ３）等之间有良好的线性关系．由Ｖｇ－Ｍ标准曲线可准确判断沸石结构状况，同时能快速准确测算试样的硅铝比等参数．

This paper first studied the variation characteristic of the chemical composition and structure of Y zeolite to adsorption retention volume(Vg)by the means of adsorption chromatography.The experiments proved that there are good linear relation of the Vg of benzene and n-hexane as well as the difference between then(△Vg)to the radio of SiO2 to Al2O3(M=SiO2/Al2O3),From the standard curve of Vg-M,the strueture state of the zeolite crystal can be judged definitively and parameters such as M value of the samples can be measured fast.
