Research Progress on Structure-Activity Relationship Between Hydrocarbon Compositions and Physicochemical Properties of Jet Fuel
Through the research and characterization of jet fuel molecular level,the hydrocarbon compositions of jet fuel are determined to further build the structure-activity relationship with physical and chemical properties,which will play an important role in guiding the prediction of jet fuel properties,R&D of rapid evaluation technology and design of high-performance jet fuel.The combustion,volatility,low-temperature fluidity,stability,lubricity,conductivity and cleanliness of jet fuel are comprehensively reviewed,as well as the qualitative correlation law between hydrocarbon compositions and general physicochemical properties,and the representative quantitative mathematical models are summarized.Meanwhile,based on summarizing the analysis methods of fuel chemical compositions,it is considered that the comprehensive two-dimensional gas chromatography is more accurate in molecular level characterization of the hydrocarbon group and carbon number distribution of jet fuel.Moreover,the development direction of prediction model is prospected and the results indicate that compared with the current modeling methods such as multiple linear regression(MLR),weighted average(WA),partial least square(PLS),modified weighted average(MWA),support vector machine(SVM),and artificial neural network(ANN)are a research focus for the future.
