近红外光谱在清洁汽油生产控制分析中的应用

介绍近红外光谱分析在清洁汽油生产控制中的应用。在标准方法的基础上，采用偏最小二乘方法建立了适合催化裂化、催化重整、90号清洁汽油和93号清洁汽油测定RON、MON、烯烃含量、芳烃含量、苯含量和氧含量的分析模型，通过大量试样对所建分析模型的可靠性进行了考察。结果表明，近红外光谱的测定结果与标准方法的测定结果有很好的一致性。近红外光谱技术的应用可以提高分析效率，降低成本，对装置的平稳运行和汽油的优化调合起到积极作用。

APPLICATION OF NEAR INFRARED SPECTROSCOPY TECHNIQUE FOR CONTROLLING CLEAN GASOLINE PRODUCTION

The application of near infrared spectroscopy (NIR) technique in quality control of clean gasoline production was introduced. Based on standard analytical methods, separate calibration models of RON, MON, olefins, aromatics, benzene and oxygen content were established for FCC naphtha, reformate, 90# and 93# clean gasoline through partial least square regression method. The calibration models were validated through comparison of the results determined by standard and NIR methods. The NIR analysis results were coincident with those using standard methods. The application of near infrared spectroscopy in gasoline production can not only raise the analysis efficiency and lower the analysis cost, but can also help to stabilize the gasoline quality and optimize the blending process.
