费托合成轻质油中烃类及含氧化合物的测定 气相色谱法

Determination of Hydrocarbon and Oxygen Components in Fischer-tropsch Synthetic Light Oil by Gas Chromatograph

本文利用带有HP-PONA毛细柱的气质联用仪和带有火焰离子检测器(FID)的气相色谱仪,采用相同色谱条件对煤基费托合成轻质石脑油和费托合成轻质油进行定性、定量分析,建立色谱图库和对应组分的族组成校正表(PONA),从而实现对各组分的准确定量分析。本法分析最高碳数达34,除准确定量正构、异构、环烷烃、芳烃以外,还可对α烯烃、β烯烃、正构醇、总含氧化合物等组分进行定量分析。

This paper uses a gas chromatograph with a HP-PONA capillary column and a FID detector,a qualitative and quantitative analysis of the synthesis of light naphtha and Fischer-tropsch synthetic oil from coal base was conducted using the same chromatographic conditions.Establish a spectral database and a PONA correction table for the corresponding components,so as to achieve an accurate quantitative analysis of each component.This method analyzes a maximum carbon number of 34,in addition to accurately quantifying positive,heterogeneous,cycloalkanes,and aromatic hydrocarbons.It is also possible to quantitatively analyze the components ofα-olefins,β-olefins,n-alcohols,and total oxygen-containing compounds.
