新型中微孔复合分子筛的研究

Study on a Novel Composite Molecular Sieve with Mesoporous and Microporous Structure

报道一种中微孔复合分子筛Y/MCM 41的研究 ,通过XRD ,SEM ,IR ,BET ,水热老化等手段对复合材料进行了表征 .研究结果表明 ,复合分子筛与机械混合物存在明显差别 。

Composite molecular sieve Y/MCM-41 was characterized by XRD, SEM, IR and BET methods. The results show that the composite material is different from the mechanical mixture of MCM-41 and NaY. The composite molecular sieve has better hydrothermal stability than the conventionally synthesized mesoporous molecular sieve MCM-41.
