| Abstract: | The separate calibration models of aromatics and olefins were established for gasoline through recursive partial least square(R-PLS)method,the application has achieved better effect in some oil refining enterprises.The calibration models were validated through comparison of the results determined by fluorescent indicator adsorption(FIA)and near infrared spectroscopy(NIR)methods.The NIR analysis results were well coincident with those of FIA method.The NIR can not only raise the analysis efficiency and lower... |
