汽油族组成的近红外光谱快速测定

Determination of Major Hydrocarbon Classes Content in Gasoline by Near Infrared Spectroscopy

以荧光指示剂吸附色谱法 (FIA)测定汽油族组成结果为基础 ,采用近红外光谱和化学计量学方法建立了快速、准确测定催化裂化馏出口汽油族组成 (饱和烃、烯烃和芳烃 )的分析模型 ;试验表明 ,该法分析速度快、重复性好、成本低 ,特别适用于生产中间控制分析。

A rapid method for determining major hydrocarbon classes content in gasoline was established by the combination of near infrared spectra(NIR) and chemometrics. The results determined by this method are in agreement with those by fluorescence indicator adsorption method(FIA). The NIR method has advantages of high speed, simplicity, better repeatability and lower analysis cost,etc. The NIR is suggested as a rapid method for the intermediate control analysis in gasoline production.
