| 摘 要： | 研究了不同载体、不同浸渍液制备的Ｐｄ催化剂对ＣＨ４还原ＮＯ的催化性能。结果表明，γ－Ａｌ２Ｏ３基催化剂在较温和的反应温度下（３５０—４００℃），具有较高的反应活性和Ｎ２选择性。而Ｐｄ／γ－Ａｌ２Ｏ３－ＺＳＭ－５催化剂在相对较高的反应温度下（４００—５００℃），显示出较高的ＮＯ转化率和Ｎ２选择性。不同的浸渍液和催化剂预处理气体，对催化剂的性能产生不同程度的影

| Abstract: | The performance of γ Al 2O 3 and γ Al 2O 3 ZSM 5 supported Pd catalysts for the selective reduction of NO by CH 4 was investigated It is found that the γ Al 2O 3 supported Pd catalysts have high NO conversion rate and high N 2 seletivity at relatively low temperatures between 350℃ and 400℃ The γ Al 2O 3 ZSM 5 supported Pd catalysts have high NO conversion rate and high N 2 selectivity at relatively high temperatures between 400℃ and 500℃ The performance of Pd supported on γ Al 2O 3 ZSM 5 is affected by variation in the treatment of gases |
