示差折光高效液相色谱法测定航空燃料和石油馏分中芳烃含量标准的建立

Construction of Standard for Determining Aromatic Hydrocarbon Content in Aviation Fuels and Petroleum Fractions Using Refractive Index High-performance Liquid Chromatography(HPLC)

航空燃料和煤油馏分中芳烃种类及其含量可在一定程度上预知和控制这些不良现象的发生。欧盟煤油芳烃含量测定方法有美国试验与材料协会标准ASTM D6379-2011《航空燃料和石油馏分中芳烃含量的测定示差折光检测器高效液相色谱法》、ASTM D1319-2014《用荧光指示剂吸附法测定液态石油产品中烃类的试验方法》。欧盟法规要求在航空燃料的分析报告中标识出单环芳烃、双环芳烃的浓度。为了适应我国航空燃料出口,有必要具备相应的检测能力。修改采用ASTM D6379-2011,建立了示差折光高效液相色谱法测定航空燃料和石油馏分中芳烃含量的标准,对试验条件和可能存在的干扰因素进行了考察,准确性能够满足要求。

The occurrence of these undesirable phenomena can be predicted and controlled to a certain extent according to the types and content of aromatic hydrocarbons in the aviation fuel and kerosene. EU methods for the determination of the aromatic hydrocarbon con- tent of kerosene include ASTM D6379-2011 ＂Determination of aromatics in aviation fuel and Petroleum Fractions--Refractive Index Detector High-performance Liquid Chromatography （HPLC）＂ and ASTM D1319-2014 ＂Standard Test Method tbr Hydrocarbon in Liq- uid Petroleum Products by Fluorescence Indicator Adsorption＂. EU regulations require that the concentration of single ring aromatics, double ring aromatics must be presented in the analysis report of the aviation fuel. In order to adapt to the export of China＇s aviation fuel, it is necessary to have the corresponding testing capabilities. The standard for determining aromatic hydrocarbon content in aviation fu- els and petroleum fractions using refractive index high-performance liquid chromatography （HPLC） is established by improving ASTM D6379-2011. The analysis of test conditions and the possible interference factors shows that the determination accuracy can meet the re- quirements.
