| 摘 要： | 用不同银含量及不同硅铝比的Ａｇ－ＺＳＭ－５分子筛催化乙醇化氧乙醛，采用高温氧化烧炭考察了银杏量，硅铝比及反应温度对催化过程中积炭行为的影响，结果表明：高ＳｉＯ２／Ａｌ２Ｏ３时积炭较慢，Ａｇ含量超过１０％，对积炭速率影响不大，反应温度高时积炭速率减慢，但是选择性及转化率降低，研究发现Ｓｎ改性的Ａｇ－ＺＳＭ－５分子筛具有较好的积炭能力。

| Abstract: | Ag-ZSM-5 was used to catalize the oxidation of ethanol to acetaldehyde,and the effects of Ag content,Si:Al ratio and reaction temperature on carbon deposit behavior in the oxidation were examined by the high temperature oxidation.The results showed that carbon deposit was slow at high SiO:Al2O3 ratio,and there were no much affection on carbon deposit at over 10% of Ag content;and carbon deposit was slow at high temperature,but selectivity and conversion were slow.It was found that Ag-ZSM-5 with being improved Sn had a good resistance to carbon deposit. |
