摘要
用傅里叶红外光谱仪,在选定的波数范围内,采用化学计量学法测量乙烯裂解汽油的二烯值。实验结果表明,该方法测量结果与参考方法(UOP326-65)测量结果之间无显著性差异,具有更好的重复性,操作方便且分析速度快,特别适用于油品生产过程中二烯值的控制分析。
Combined with stoichiometric method, the diene value in cracking gasoline was determined by Fourier Transform Infrared Spectroscopy at selected wavenumber region. The values measured by IR coincided with those of the reference method (UOP326 - 65). The new method has advantages of better repeatability, facility and short analysis time, and it is suitable especially for control analysis of diene value in processing of gasoline.
