| 中文摘要 |
| 考察了添加Al2O3对硅藻土的孔容、平均孔径及比表面的影响.并研究了负载型Ce-Cr、Ce-Cr-Mn等复合氧化物催化剂对丙酮、正丁胺、甲苯氧化反应的活性.氧化活性的顺序为:Ce-Cr-Mn-K≈Ce-Cr-Mn≈Ce-Cr>Mn>Cr>Ce.而且能够抑制正丁胺氧化过程NOx的形成,正丁胺氧化NOx控制能力为:Ce-Cr-Mn-K>Ce-Cr-Mn>Ce-Cr>Ce. |
| 英文摘要 |
| The influence of addition of alumina on the pore volume, mean pore size and surface area of diatomite was investigated. The activity of Ce-Cr, Ce-Cr-Ma, etc. complex oxide supported catalysts for the oxidation of acetone, butylamine and toluene was studied. The order of oxidation activity was deterrmined to be: Ce-Cr-Mn-K ≈Ce-Cr-Mn≈Ce-Cr>Mn>Cr > Ce. The formation of NOx in the oxidative reaction of butylamine can be retarded. The order of NOx formation retarding ability of the catalysts was: Ce-Cr-Mn-K > Ce-Cr-Mn > Ce-Cr > Ce. |
