1.
It seems that the dealumination and the silicon substitutionof Y zeolites with ammonium hexafluorosilicate undergoes two steps,andthe dealumination rate is much more rapid than that of silicon substitu-tion.
用氟硅酸铵溶液处理NaNH_4Y可制得新型超稳Y沸石FSEY,本文通过比较不同条件下制得的FSEY的相对结晶度、晶胞大小及硅铝比,探讨了氟硅酸铵脱铝补硅机理。

HMCM-22 zeolite was modified with ammonium hexafluorosilicate and characterized by temperature-programmed desorption of ammonia and pyridine adsorption infrared spectroscopy.
用氟硅酸铵对HMCM-22分子筛进行了改性处理,并采用氨程序升温脱附和吡啶吸附红外光谱法测定了其酸性。
3.
hydrothermal,acid and ammonium hexafluorosilicate(AHFS)treatments were used to treat the nanoscale HZSM-5,and the means of XRD,NH3-TPD,XRF,IR and N2 adsorption were used to characterize these treated samples,in order to investigate the effects of dealumination methods on the structure and properties of nanoscale HZSM-5,such as acidity,molar ratio of Si/Al,surface area and pore volume.
分别采用水热处理、酸处理和氟硅酸铵(AHFS)对纳米HZSM-5分子筛进行脱铝,并采用XRD、NH3-TPD、XRF、IR和N2吸附等方法对这些样品进行了表征,考察了脱铝方法对纳米HZSM-5的结构、酸性、硅/铝摩尔比、比表面积和孔体积等物化性质的影响。
