摘　　要：汽、柴油是国家重要的能源,汽、柴油质量对环境治理、群众健康以及人身安全有重要影响,因此国家对汽、柴油中各项指标的范围做出了详细规定,包含辛烷值、芳烃、烯烃、苯、馏程等30项指标。传统方法对汽、柴油参数的测定需要使用十六烷值测定仪、气相色谱仪等多种仪器,其时间长、效率低。目前傅里叶变换近红外光谱方法能够同时定量分析以上参数,具有测量参数多、速度快且测量准确度高的优点,在石油产业中得到了迅速的推广及应用。本文阐述了傅里叶变换近红外光谱方法的研究进展,介绍了傅里叶变换近红外光谱仪的基本原理、装置的主要结构及关键技术,以及傅里叶变换近红外光谱仪分析汽、柴油成分方法,并对未来的研究和应用前景进行了展望。Gasoline and diesel are important energy sources for China. The quality of gasoline and diesel has an important impact on environmental governance, public health and personal safety. Therefore, China has made detailed regulations on the scope of various indicators in gasoline and diesel, including octane number, aromatic hydrocarbons,olefins, benzene, distillation range and other 30 indicators. The traditional method for the determination of gasoline and diesel parameters requires the use of cetane number analyzers, gas chromatographs and other instruments, which take a long time and have low efficiency. At present, the Fourier transform near-infrared spectroscopy(FT-NIRS) method can quantitatively analyze the above parameters at the same time, and has the advantages of many measurement parameters, fast speed and high measurement accuracy, and has been rapidly popularized and applied in the petroleum industry. This paper expounds the research progress of FT-NIRS, introduces the basic principle of FT-NIRS, the main structure and key technology of the device, and the method of FT-NIRS to analyze the composition of gasoline and diesel, and the future research and application prospects are prospected.
