Study on Spontaneous Combustion Mechanism of Oil Containing Sulfur Based on Thermal Analysis

    摘要
  • 摘要: 采用Q600型同步热分析仪对5种不同粒径的FeS样品进行了热分析试验, 并通过TG和DSC研究了含硫油品的自燃特征。结果表明, FeS对温度变化不灵敏, 一般在250℃以上才开始氧化, 而且氧化过程缓慢; 颗粒尺寸对FeS的受热氧化性质影响显著, 随着颗粒的增大, FeS氧化初始温度升高, 整个氧化周期的温度范围变宽; 升温速率慢, 有利于FeS的受热氧化。

     

    Abstract: By making use of Q600 Simultaneous TG—DSC.thermal analysis experiments of 5 FeS samples with different diameters are completed.Spontaneous combustion mechanism of the oil containing sulfur is researched based on the experimental results of TG and DSC.Experimental results show that FeS sample is not sensitive to the change of temperature.In generally, oxidative temperature of FeS sample is more than 250℃and oxidative rate is slow.Sample diameter plays an important role in oxidative tendency of FeS sample.With the increase of sample diameter, the oxidative temperature of FeS sample increases and the range of oxidative temperature expands.Heating rate also influences on oxidative tendency of FeS sample and the oxidative tendency is more obvious in case of slow heating rate.
