【摘要】 利用GC/MS分析了30种喷气燃料的烃族组成结果,详细确定了每种燃料的链烷烃、一环环烷烃、二环环烷烃、三环环烷烃、单环芳烃和双环芳烃等组成。根据ASTM D2887利用气相色谱法测定喷气燃料的馏程。根据其烃族组成和馏程建立了一种燃料氢含量的估算方法,并对该估算方法的准确度进行分析。结果表明,利用烃族组成及模拟蒸馏中沸点的数据估算氢含量的方法与元素分析法测定结果一致,可利用该方法对喷气燃料氢含量进行估算。更多还原

【Abstract】 Fuel composition was expressed in terms of the abundances of hydrocarbon compound classes(alkanes,mono-cycloalkanes,di-cycloalkanes,tri-cycloalkanes,monoaromatics and diaromatics aromatics) and was determined by GC / MS.Distillation data of the jet fuel was measured by the standard ASTM D2887.Hydrogen Content evaluation of jet fuels was established according to its hydrocarbon compound classes and distillation data,and the accuracy of the method was analyzed.The method of use of hydrocarbon composition and simulated distillation boiling point of the data to estimate the hydrogen content was consistent with the determination of elemental analysis results.更多还原
