| 摘 要： | 采用蒸气相法使无定形凝胶在水蒸气中结晶形成ZSM-5分子筛,通过X射线衍射、红外光谱、热重、扫描电镜以及能量色散型X射线荧光分析对合成的分子筛进行了表征.结果表明,蒸气相法比水热法更易合成出粒径均匀、形貌规则的小颗粒分子筛(粒径为150～250nm),将其负载Mo后用于甲烷无氧芳构化反应中,表现出更好的催化性能,初期甲烷转化率达17.5%,同时表现出更高的稳定性和容炭能力.

| Abstract: | ZSM-5 zeolite was prepared from the amorphous SiO2:Al2O3:TPAOH:Na2O system in H2O vapor phase.The obtained samples were characterized by X-ray diffraction,Fourier transform infrared spectroscopy,scanning electron microscopy,etc.Compared with the hydrothermal method,using the vapor-phase method could easily synthesize ZSM-5 zeolite with uniform particle size.The particle size was between 150 and 250 nm.It also showed a better catalytic performance with CH4 conversion as high as 17.5% and better life time. |
