| 摘 要： | 采用红外光谱方法考察了催化剂样品中的探针分子吡啶在程序升温脱附过程中的谱图变化，将红外光谱的特征峰强度与样品温度进行关联，并进行微分处理。从而得知铕增强了Ｍｏ／ＨＺＳＭ－ ５ 催化剂的Ｂ 酸强度，而对Ｌ 酸强度无影响。

| Abstract: | The surface acidic properties Mo/HZSM-5 and Mo-Eu/HZSM-5 catalysts have been investigated by means of IR.The absorbance of characteristic peaks and the temperature of samples were correlated.The data of absorbance and temperature were treated by differentiation.The results show that strength of Brnsted acid sites of Mo-Eu/HZSM-5 zeolite is enhanced and strength of Lewis acid sites of the catalyst is not affected by loaded europium. |
