摘要
利用草酸和磷酸氢二铵(ADP)对NaY分子筛改性,采用傅里叶变换红外光谱(FTIR)、X-射线衍射(XRD)、热分析及等离子体发射光谱(ICP)等表征技术,探讨改性对NaY分子筛的结构和酸性的影响。结果表明,草酸和磷酸氢二铵对NaY分子筛的改性在不改变分子筛的结构的基础上可以有效地降低分子筛的酸性。
The structure and acidity of NaY zeolite modified by oxalic acid and diammonium hydrogen phosphate （ADP） were studied, The acidity of NaY zeolite and dealuminated zeolite are investigated by Fourier transform infrared spectrophotometry （FTIR）, ICP, and thermal analysis, The changes of the structure of the modified zeolites were studied by X-ray diffraction （XRD） analysis. Both the modification techniques can reduce the acidity of NaY zeolite without any change on the structure,
