| 摘 要： | 经酸交换，水蒸气处理及加入粘合剂后的催化剂表面酸性均比Ｈβ原粉要低，主要是Ｂ酸变化较为明显。β沸石在酸洗过程中，酸量降低较大，Ｂ酸下降幅度较大，这可能是与其脱铝程度明显有关。经水蒸汽处理后，除在４００℃水蒸汽处理下酸量变化不大外，其余均有所下降。

| Abstract: | A study of the hydration of propylene over acidic beta zeolite catalyst shows that the catalytic activities are determined by their effective Bronsted acidity.Using XRD,SEM,IR, TPD,AAS,etc,the effects of structure and acidity changes of modified beta zeolite catalysts on the reaction are studied, the results indicate that the active site is the weak Bronsted acid centre. |
