摘    要:以微孔分子筛HY浆液为母液,合成介孔一微孔复合分子筛MCM-41-HY。通过XRD、NH3-TPD和N2吸附一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。

关 键 词:催化剂工程  MCM-41-HY  复合分子筛  介孔-微孔分子筛  酸强度  水热稳定性

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
Keywords:MCM-41-HY
