| 摘 要： | 以微孔分子筛HY浆液为母液,合成介孔-微孔复合分子筛MCM-41-HY。通过XRD、NH_3-TPD和N_2吸附-脱附等手段对复合材料进行了表征,并对复合分子筛的水热稳定性进行了考察。结果表明,复合分子筛MCM-41-HY具有中孔分子筛MCM-41和微孔HY型沸石的特点,并且与纯MCM-41分子筛相比,复合分子筛的酸强度明显增强,水热稳定性提高。

| Abstract: | A new meso-microporous MCM-41-HY zeolite was prepared using HY zeolite as the mother liquor and characterized by XRD, NH3-TPD and N2 adsorption-desorption. Hydrothermal stability of the zeolite was investigated. The results showed that MCM-41-HY zeolite exhibited the properties of both mesoporous MCM-41 and microporous HY, with stronger acidity and better hydrothermal stability than pure mesoporous MCM-41 |
