| 摘 要： | 在２．９％（ｗｔ）Ｎｉ／Ａｌ２Ｏ３催化剂上用ｉｎｓｉｔｕＦＴＩＲ研究了ＣＨ４部分氧化制合成气的反应机理。结果表明，催化剂表面的活性碳物种与化学吸附的Ｏ原子反应生成ＣＯ；ＣＨ４／Ｏ２（２：ｌ）混合气在催化剂表面吸附的ＩＲ谱图表明只有Ｈ２Ｏ和ＣＯ２存在，说明ＣＨ４和ＣＯ２的重整反应没有发生。因此，我们认为ＣＯ和Ｈ２是一级产物。

| Abstract: | The mechanism of the CH 4/O 2 to syngas reaction has been investigated by FT IR over a 2.9%(wt)Ni/Al 2O 3. IR spectra of adsorption of CH 4 indicate that chemisorbed O atoms can react selectively with active carbon species (arising from CH 4 decomposition) to give CO. IR spectra of adsorption of CH 4/O 2(2:1 mole ratio) mixture show that CO 2 and H 2O are the detectable products with no CO, revealing that the reforming of remaining CH 4 would not take place. We propose that CO and H 2 are primary products in this reaction |
