吸热型碳氢燃料热安定性研究

Study on thermal stability of endothermic hydrocarbon fuel

采用静态法测定了自行研制的吸热型碳氢燃料NNJ-150在加强氧化条件下的热安定性能,用气质联用检测了燃料热处理前后组分的变化.结果表明,加强氧化达到约2.5h后燃料中有明显沉积物出现,气质分析结果证实燃料中有氧化物生成.在相同实验条件下,评价了7种抗氧剂的效果,合适的抗氧剂可以使燃料的氧化安定性有一定程度的提高.

The thermal stability of endothermic hydrocarbon fuel was studied by static state method under strengthened oxidation condition. The components of fuel before and after treatment were analyzed on GC-MS. The results show that some deposits appeared after thermal-treatment for about 2.5 hours, and oxide can be found in the fuel. Effects of several antioxidants for the fuel were measured under the same experiment condition, which shows that addition of suitable antioxidants can improve the thermal stability of endothermic hydrocarbon fuel..
