【摘要】 模拟油品储罐中硫化亚铁的生成方式 ,研究了H2 S气体在没有氧气存在的条件下与油品储罐内壁腐蚀产物-Fe(OH) 3 、Fe2 O3 和Fe3 O4发生反应及反应产物硫化亚铁的自燃性 .结果表明 :油品储罐中腐蚀产物Fe(OH) 3 、Fe2 O3 和Fe3 O4与H2 S在无氧条件下均可发生放热反应生成硫化亚铁 ,且生成的硫化亚铁与空气接触会发生氧化反应放出热量 ,热量聚集使油品温度上升是引起油品自燃并导致油品储罐发生火灾和爆炸事故的主要原因 .但不同生成方式所生成的硫化亚铁的氧化速度不同 ,其自燃性也不同 .更多还原

【Abstract】 To simulate the formation process of ferrous sulfide in oil tank,the reactions of iron hydroxide,iron oxide red,iron oxide black with hydrogen sulfide under the conditions of oxygen free at low temperature were studied,and then the spontaneous combustion of the formed ferrous sulfide was also observed.The results show that iron hydroxide,iron oxide red and iron oxide black can react with H 2S exothemically respectively in a flow of hydrogen sulfide of 300 ml/min.The reaction products then can react exothermically with oxygen in air flow of 300 ml/min.It follows that the iron hydroxide,iron oxide red and iron oxide black in oil tank can react with hydrogen sulfide to product ferrous sulfide and then ferrous sulfide can react with oxygen in air to release heat.But the oxidation rate and spontaneous combustion behavior of ferrous sulfide in different environments was different.更多还原
