摘要: 利用GC/MS分析了80个喷气燃料样品的烃族化学组成,将其分为直链烃、异构烃、环烷烃、芳烃、十氢萘五大类,并测定了燃料的密度、苯胺点、热值、冰点、闪点及沸程等主要理化性质。构建了喷气燃料组成和性质关系的数据库,考察了喷气燃料的烃族组成及沸程对各种性质的影响。结合Cookson等的理论,建立了八个模型方程,通过多元线性回归预测烃族化学组成与理化性质关系, 与已报道的其他方程比较,新模型的相关系数明显提高。Abstract: The chemical composition of 80 jet fuel samples was analysed by GC/MS, which is grouped into five categories of hydrocarbon compounds including n-paraffins, isoparaffins, cyclo paraffins, hydroaromatic and decalin. Several physical properties including density, flash point, freezing point, heating value and boiling range were measured by the standard ASTM methods. The database of compositionproperty relationship of the jet fuels was built up. The effect of chemical composition and boiling range on the physical properties was discussed. Combined with the Cookson′s models, 8 models were developed to predict the relationship of compositionproperties by multiple linear regressions (MLR), which gives a better prediction than the MLR correlations reported.
