摘　　要：模拟含硫油品储罐中硫铁化物的生成方式,研究了硫化氢气体在无氧条件下,与不同温度及不同相对湿度的四氧化三铁发生硫化反应所生成硫化产物的自然氧化性,结果表明,样品的相对湿度对其生成的硫化产物的自然氧化倾向性有重要的影响。室温下且相对湿度在5%～20%的条件下与50℃以上且相对湿度在10%～20%的条件下所生成的硫化产物自然氧化性最强,对含硫油品储罐安全运行构成的威胁最大。无水或相对湿度大于20%条件下所生成的硫化产物的氧化速度缓慢,基本不影响储罐的安全运行。The formation of sulfide in oil tank is simulated. The reaction of hydrogen sulfide with iron oxide black of different temperature and different relative humidity under the conditions of oxygen free, and the oxidation tendency of formed sulfide are studied. The result shows that the relative humidity of the sample plays an important role in oxidation tendency of sulfide. The strongest oxidation tendency of sulfide formed at relative humidity of 5%-20% at room temperature and at relative humidity of 10%-20% above 50℃, which will result in the most serious threat to the safe running of oil tanks. The oxidation tendency of sulfide formed at relative humidity of 0% or above 20% is weak,and there is no risk to the safe running of oil tanks.
