摘要:

为考察烃类族组成对喷气燃料理化性质的影响,分别将煤基航煤和生物航煤加入3号喷气燃料中,按照GB 6537-2018《3号喷气燃料》规定的实验方法对喷气燃料的17项理化性质进行了检测。结果表明,烃类族组成是喷气燃料8项理化性质的主要影响因素,随着链烷烃质量分数的增加或者环烷烃质量分数的降低,10%回收温度、50%回收温度、终馏点、冰点、-20 ℃运动黏度和烟点基本单调降低,而密度和体积净热值单调升高;烃类族组成是其余9项理化性质的非主要影响因素,链烷烃质量分数的增加或降低均会导致闪点、萘系烃体积分数降低,链烷烃和环烷烃质量分数对质量净热值、腐蚀性、热安定性、胶质质量浓度、水反应界面情况、水反应分离程度和水分离指数几乎没有影响。在航空替代燃料与喷气燃料掺配使用时,可以根据烃类族组成对喷气燃料理化性质的影响规律对掺配后燃料的理化性质进行一定程度的预测,从而减少实验次数,提高效率。

Abstract:

In order to study the effect of hydrocarbon group composition on physical and chemical properties of jet fuel, the coal?based kerosene and biogenic aviation fuel were added to No.3 jet fuel respectively, and the seventeen physical and chemical properties of jet fuel were tested according to the experimental methods specified in GB 6537—2018《Jet Fuel No.3》. The results showed that hydrocarbon group composition was the primary factor affecting 8 physicochemical properties of blended jet fuel. As the mass fraction of paraffin increased or the mass fraction of naphthene decreased, the 10% recovery temperature, 50% recovery temperature, final boiling point, freezing point, kinematic viscosity at -20 ℃, and smoke point generally decreased monotonically, while density and net calorific value per volume increased monotonically. Hydrocarbon group composition was a non?primary factor affecting the remaining 9 physicochemical properties. An increase or decrease in paraffin mass fraction led to a decrease in flash point and naphthalene hydrocarbon volume fraction, whereas paraffin and naphthene mass fractions had negligible effects on net calorific value per mass, corrosiveness, thermal stability, gum mass concentration, water reaction interface condition, water reaction separation degree, and water separation index. When blending aviation alternative fuels with traditional jet fuel, the physicochemical properties of the blended fuel can be predicted to a certain extent based on the influence rules of hydrocarbon group composition on jet fuel properties, thereby reducing experimental trials and improving efficiency.
