摘要
采用GC/MS与偏最小二乘法结合的方法测定了汽油馏分、柴油馏分、润滑油馏分、VGO馏分及渣油馏分的累积收率以及汽油馏分、柴油馏分的相对密度,建立了采用MS数据预测这 5种馏分油累积收率和汽油馏分、柴油馏分相对密度的PLS校正模型。验证集结果表明:GC/MS方法与标准方法测定的结果之间无显著性差别。用GC/MS方法可以实现馏分油累积收率及性质的快速测定,与标准方法相比,大大缩短了分析时间。
The sum yields of five wide-cut fractions (gasoline fraction, diesel fraction, lube oil fraction, VGO fraction and residue fraction) and the relative density of gasoline fraction and diesel fraction were determined with mass spectrometric spectra from capillary column. Seven partial least squares calibration models with small deviations were established. The results of paired t-test of validation sample set show that these seven models can be used to predict the sum yields,and property of wide-cut fractions. In comparison to standard methods, the gas chromatography/mass spectrometric method is rapid, simple and needs a little sample.
