偏最小二乘-近红外光谱测定抚顺石油二厂汽油辛烷值

Determination of Octane Numbers of Gasoline from Fushun Refinery No.2 by PLS and NIR Spectroscopy

对来自抚顺石油二厂的汽油样品进行近红外光谱分析,使用偏最小二乘算法建立近红外谱图与辛烷值的关联模型。检测表明,用近红外光谱检测石油二厂汽油样品辛烷值的误差在标准方法规定的再现性要求之内,证明了用近红外光谱技术分析石油二厂汽油辛烷值的可行性。

The octane numbers of gasoline from Fushun refinery No .2 were determined by using partial least squares （PLS） and near infrared （NIR） spectrometer. The predictive model of octane numbers of gasoline was developed by using PLS. Experimental result indicates that, the NIR spectrometer combining with PLS can be used for quantitative analysis of gasoline octane.
