不同湿度的H_2S在Fe_2O_3表面的吸附反应研究

The Performance of Different Humidity Sulfured Hydrogen Absorbed on the Surface of Ferrous Oxide

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H2S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。

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.
