| 摘 要： | 本文考察了Ａｎ－Ｍｎ，Ａｇ－Ｃｏ和Ａｇ－Ｃｅ复合氧化物上ＣＯ，丙酮和吡啶的催化氧化性能，结果表明，双组分Ａｇ－Ｍｎ／Ａｌ２Ｏ３和Ａｇ－Ｃｏ／Ａｌ２Ｏ３催化剂的氧化活性均高于单组分Ａｇ／Ａｌ２Ｏ３．在Ａｇ－Ｃｅ／Ａｌ２Ｏ３催化剂上，ＣＯ氧化反应的速率言程可用ｒ＝ｋＰｏ２＾ｍＰＣＯ来表示，随着催化剂中氧化铈含量的增加，对氧的反应级数明显下降。

| Abstract: | Catalytic oxidation of CO,acetone and pyridine on Ag-Mn,Ag-Co and Ag-Ce composite oxides was studied. The Ag-Mn/Al2O3 (4 : 1) and Ag-Co/Al2O3(4 : 1) catalysts exhibit higher activity than Ag/Al2O;i ,Mn/Al2O3 or Co/Al2O3. The kinetics equation of CO oxidation on Ag-Ce/Al2O3 is expressed as r = kPo2mPco and the reaction order m de creaes as the amout of Ce increase. Oxidation activity of catalysts was directly proportion to their NOx control ability for pyridine oxidation. |
