| 摘 要： | 本文运用固定床微反技术考察了Ｃｕ，Ｆｅ，Ｍｎ，Ｃｒ，Ｃｏ和Ｎｉ负载（ＺｒＯ２载体）氧化物对ＣＯ＋ＮＯ（Ｏ２）反应的催化活性。研究了ＮＯ和ＣＯ在不同比例时，催化剂对Ｎ２Ｏ和Ｎ２生成的影响。结果表明，在ＮＯ＋ＣＯ反应中，ＮＯ和ＣＯ的比例对催化剂活性和Ｎ２Ｏ，Ｎ２生成均有明显的影响，ＣｕＯｘ／ＺｒＯ２催化剂的活性最高；Ｎ２Ｏ是ＮＯ＋ＣＯ反应的中间产物，低温或ＮＯ过量时有利于生成Ｎ２Ｏ，高温或ＮＯ不足时有

| Abstract: | The catalytic activity of ZrO2-supported Cu, Fe, Mn, Cr, Co or Ni oxide catalysts for NO + CO reaction and CO + O2 reaction was investigated using fixed bed microreaction technigue. The effects of catalysts on formation of N2O and N2 were also studied when the ratios of NO and CO is different . The results showed that the ratios of NO and CO have remarkable effects of the activity order of these catalysts and the selectivities of N2O or N2 formation. N2O is intermediate of NO + CO reaction. Lower temperature of NO overcharge will increase the formation of N2. In CO + O2 reaction, the activity order of the catalysts is CuOx > CoOx > MnOx > FeOx > NiOx > CrOx . |
