Abstract: The sulfured hydrogen gas adsorbed on the surface of ferrous oxide was investigated．The effect of temperature，humidity of sulfured hydrogen gas，volume ratio of sulfured hydrogen gas and humidity of ferrous oxide was discussed．The results show that decreasing sulfide temperature，increasing humidity and volume ratio of sulfured hydrogen gas would enhance the absorb reaction．And when the humidity of ferrous oxide was 10%,the absorb volume ratio of sulfured hydrogen gas is larger than other humidity of ferrous oxide．Another conclusion is that dry sulfured hydrogen gas adsorbed on the surface of
ferrous oxide and the product is sulfide ferrous，which can make an effect of corruption on the equipment．

Key words: Absorb reaction , Humidity of sulfured hydrogen gas , Humidity of ferrous oxide , Sulfide reaction

摘要： 研究了H₂S在Fe₂O₃表面的吸附反应过程，考察了温度，H₂S湿度，H₂S起始体积分数，Fe₂O₃湿度对吸附反应的影响。结果表明：温度的降低，H₂S湿度和起始体积分数的增加，均促进吸附反应；而且当Fe₂O₃的湿度为 10%时，吸附 H 2 S的体积分数最大。干燥的H₂S在干燥的Fe₂O₃表面也发生吸附反应，生成 FeS，对设备产生一定的腐蚀作用。
