用低温氮物理吸附法测定了富硅 Y 型沸石的总表面积、二次孔表面积和微孔体积;用吡啶吸附脱附前后的红外光谱法表征了富硅 Y 型沸石骨架中方钠石笼的完整程度;获得了有关富硅 Y 沸石孔结构性质的信息。
The total surface area, secondary pore surface area and micropore volume of silica-rich Y zeolite were determined by low temperature nitrogen physical adsorption method. The completeness of the soda limestone cage in silicon-rich Y-type zeolite skeleton was characterized by infrared spectroscopy before and after adsorption and desorption of pyridine Degree; obtained information on the pore structure properties of Si-rich Y zeolites.
