| 摘 要： | 运用色谱微反联用技术研究了二氯甲烷在ＭｘＯｙ／ＺＳＭ－５沸石催化剂上的催化氧化．实验发现，ＭｘＯｙ／ＺＳＭ－５催化剂可以在较低温度下表现出较高的反应活性，如ＣｒＯ３／ＺＳＭ－５－（１）在３００℃即达１００％。本文试验结果表明，ＭｘＯｙ／ＺＳＭ－５的催化活性次序为；ＣｒＯ３／ＺＳＭ－５＞ＺｒＯ２／ＺＳＭ－５＞Ｖ２Ｏ５／ＺＳＭ－５。实验还揭示，ＺＳＭ－５沸石中Ｂ酸中心浓度的不同明显影响催化剂的活性与选择性．

| Abstract: | Catalytic decomposition of methylene chloride was studied in a flowing fixed-bed reactor. Three different MxOy/ZSM-5 Catalysts,CrO3/ZSM-5, ZrO2/ZSM-5, V2O5/ZSM-5 were prepared and their activities and seletivities measured. The catalytic activity decreased in the order:CrO3/ZSM-5>ZrO2/ZSM-5>V,O./ZSM 5. Furthermore,the concentration of Bronsted acid in zeolite ZSM-5 remarkably influence the catalytic activity and selectivity in the reaction of oxidative destruction of methylene chloride. |
