| 摘 要： | 硫铁化物的氧化放热被认为是引起含硫油品储罐火灾与爆炸事故的主要原因.储罐内壁铁的主要腐蚀产物Fe2O3、Fe3O4、Fe(OH)3与H2S气体反应可以生成不同形式的硫铁化物,同时H2S气体溶解在水中生成的氢硫酸与内壁铁也可以生成硫铁化物.考察了不同方式生成的硫铁化物的氧化倾向性,并对其硫化产物进行了扫描电镜分析.结果表明,Fe2O3、Fe3O4生成的硫铁化物氧化倾向性较高,结构的不同可能是造成其自燃性差异的主要原因.

| Abstract: | Thermal oxidation of the iron sulphides is regarded as the main cause of tank fire and explosion accidents. Iron sulphides generate when Fe2O3, Fe3O4 and Fe(OH)3 as a predominant corrosion product in storage tank reacts with hygrogen sulphide, and hydrogen sulphide dissolving in form hydrosulphuric acid reacts with iron to give iron sulfides.The oxidation tendency of iron sulfides which generated from different mode are inspected, and the sulfurization are researched by electron microscope. The research res... |
