| 摘 要： | 研究了Ｈ２Ｓ对低碳钢在焦炉煤气中腐蚀动力学的影响，证实在Ｈ２Ｓ含量为０．１５ｇ／ｍ＾３时电极过程的控制步骤出现明显的转化，「Ｈ２Ｓ」〈０．１５ｇ／ｍ＾３为阴极过程控制，「Ｈ２Ｓ」〉０．１５ｇ／ｍ＾３为阳极过程控制，用直接证据证明在高Ｈ２Ｓ含量的煤气中低碳钢能够在表面形成和密的保护膜，并且从理论上解释了这些现象。

| Abstract: | The effect of H2S on the corrosion dynamics of low carbon steel in coke oven gas was investigated. It is showed that the electropolar process controlling step changes remarkably at 0.15g/m3 H2S,corrosion controlling step is cathodic reactions at<0.15g/m3 H2S and anodic reactions at>0.15g/m3H2S.There is evidence that the dense protective film forms on the surface of low carbon steel in high H2S coke oven gas. The phenomena are theoretically explained. |
