Based on near-infrared (NIR) spectroscopy and Monte Carlo virtual spectrum identification method, a fast analytical tool is presented for rapid prediction of key gasoline properties; 542 reformed gasoline samples were collected to establish NIR spectroscopic database for determination of research octane number and hydrocarbon groups. The prediction accuracy of the Monte Carlo method is slightly lower than that of PLS, but the method does not need modeling and model maintenance, the results show that the standard deviation of prediction of paraffin, isoparaffin, olefins, aromatics, naphthenes, and octane number are 0.31%, 0.47%, 0.21%, 0.43%, 0.67% and 0.25, respectively, which meet the requirements of fast assessment. This method can significantly reduce the maintenance of traditional multivariate calibration.

“…IR and NIR offer the possibility of rapid determination of crude oil parameter. Several researchers have studied their application to refinery and petrochemical products’ properties, such as octane number of gasoline and diesel properties . At the present time, mid-IR (MIR) has been receiving results as good as those of NIR. , The application of attenuated total reflection (ATR) accessory can simplify and expedite the MIR measurement to a considerable degree .…”

Total acid number (TAN) is one of the most important parameters for petroleum. The combined use of multivariate calibration and mid-infrared attenuated total reflection spectroscopy allows it to be estimated accurately. The calibration models of acid number have been established by partial least-squares (PLS). The predictive ability of the IR technique with regard to the TAN have been explored. The results predicted by this method were very close to those determined by standard methods. Compared with Standards, this method is provided with advantages such as high speed, simplicity, no pretreatment, and good-repeatability.
