摘要
介绍了近红外光谱(NIR)分析技术在线测定催化汽油样品烯烃含量的方法。结果证明:近红外光谱分析技术的分析结果能够完全满足生产中的精度要求,再现性和重现性也远远优于GB的要求。另外,该方法除具有测量速度快的优点之外,还具有分析成本低、无污染、操作简单方便等特点,能对样品进行准确、经济的分析。
In this paper, a method for the determination of olefin of cracking gasoline by NIR is presented. The result of NIR can meet the precision request in production and has higher repeatability and reproductivity than GB method. NIR method has the advantages of fast speed, low cost, no pollution and easy use. The accurate and economical analysis can be realized.
