摘要
石脑油是石油化工中最重要的化工原料,对其PNA(烷、环、芳烃)值的准确分析是控制毫秒炉加工工艺,从而取得最佳经济效益的主要依据。目前国际上主要有以Packard 412机为代表的多柱切换族分离,及以5880A HP(85)软件为代表的高效毛细管柱的组分分离两种,后者明显优于前者。要完全分离石脑油中数百个组分,这在技术上是困难的,而在生产应用中又无必要。在分离研究中只要着眼于PNA族之间的最大分离,就能取得准确的PNA值。 由于烷、环。
A software has been developed to select the optimal operation conditions for separation of PNA in naphtha based on the prediction of retention indices. By using an ordinary GC instrument and a domestic capillary column better results were obtained from this software than from HP 5880A HP (85) in determining PNA in naphtha. The software was testified in practical application of naphtha analysis.
