| 摘 要： | 利用空速、氧醇比、反应温度研究了Ａｇ／ＺＳＭ－５分子筛催化剂对催化乙醇制乙醛的反应活性的影响。结果表明，该催化剂在３４０℃就有相当高的催化活性：乙醛产率达９３．０％（空速为９．６ｓ￣（－１），氧醇比为０．５０）。ＸＲＤ和ＳＥＭ等研究表明，Ａｇ是以单质的形式负载在ＺＳＭ－５分子筛上。由此提出催化反应机理。

| Abstract: | The catalystic oxidation of ethonol to acetaldehyde for measuring catalytic activity over Ag/ZSM-5 zeolite catalyst is studied. The effects of space velocity, mole ratio of oxygen to ethanol, reaction temperature on the catalytic activity are investigated. The experiment results show that there are high catalytic activity on the catalyst: 93.0% yield of acelaldehyde at 340t reaction temperature. Ag is on the ZSM-5 zeolite(treated) by XRD and SEM studies. |
