摘要：利用微反－色谱技术考察了Ｃｕ－Ｍｎ－Ｏ及Ｃｕ－Ｍｎ－Ｃｅ－Ｏ催化剂的甲苯完全燃烧活性；通过改变氧的浓度，研究了ＣｅＯ＿２对Ｃｕ－Ｍｎ－Ｏ催化剂性能的影响；用ＴＰＲ、ＴＰＯＴ和氢氧滴定法测定了催化剂的表面性能。结果表明，ＣｅＯ＿２能够增加催化剂表面的贮氧量，提高吸氧能力，改进供氧性能，进而提高Ｃｕ－Ｍｎ－Ｏ催化剂在低氧比时的无化活性，也能使还原后的Ｃｕ－Ｍｎ－Ｏ催化剂具有良好的再生氧化活性。
The combustion activity of toluene over the catalysts,Cu-Mn-O and Cu-Mn-Ce-O were examined with the micro-reactor-chrom technique. Through the change of oxygenconcentration in gas phase,the effects of CeO_2 on catalytic performance have been studied;byTPOT,TPR dnd hydrogen-oxygen titration,the properties of surface were measured.The re-sults showed that CeO_2 could increase the amount of oxygen stored on the surface and the a-bility of adsorbing oxygen ,and promote greatly the oxidation activity of the catalysts in low-ratio oxygen。Additionally,CeO_2 can make the reduced catalyst have better resoring oxidationactivity.
