Abstract Stannous chloride (SnCl 2 ) was firstly used as an inhibitor to prevent coal oxidation. Thermal analysis was used to study the influence of SnCl 2 . Weight increase due to oxygen chemisorption, the ignition temperature, the burnout temperature and heat released during the whole process were evaluated as main parameters. The results indicated that the addition of SnCl 2 leads to significant reduction in the percentage of mass increase. The presence of SnCl 2 caused increase in the ignition temperature and decrease in the heat released. However, there is probably no effect of SnCl 2 on the burnout temperature. The mechanism of the SnCl 2 suggested that the addition of SnCl 2 to the coal oxidation mainly influence the oxygen chemisorption by consuming more oxygen. Thus, SnCl 2 can be recommended as effective inhibitor to coal oxidation.

氯化亚锡对煤低温氧化反应的影响

摘要 氯化亚锡(SnCl 2 )最早被用作防止煤氧化的抑制剂。热分析用于研究SnCl 2 的影响。氧化学吸附导致的重量增加、着火温度、燃尽温度和整个过程中释放的热量作为主要参数进行评估。结果表明，SnCl 2 的加入导致质量增加百分比的显着降低。SnCl 2 的存在导致着火温度升高和释放的热量降低。然而，SnCl 2 对燃尽温度可能没有影响。SnCl 2 的作用机理表明，在煤氧化中加入SnCl 2 主要通过消耗更多的氧来影响氧的化学吸附。因此，可以推荐SnCl 2 作为煤氧化的有效抑制剂。
