| Abstract: | The methods of rapidly determining octane number and PNA composition of reforming stock and reformed gasoline by online near infrared spectrometer are introduced. The near infrared spectrums of reforming stock and reformed gasoline are collected by using CCD in near infrared spectrometer. They were differentiated and then standardized according to SNV requirements. Calibration models are established for octane number and straight chain paraffin hydrocarbon, partial least square method. Now the naphthenic hydrocarbon and aromatic hydrocarbon coming from C4-C10 by prediction are up to the requirements in the standard. |
