The analysis results obtained using Zebron ZB-1701 and ZB-1 GC columns together enabled the GC×GC-FID system to unravel molecular structures of oxygenated compounds in a coal-derived middle distillate. It also shows that the oxygenated structures mainly consist of phenolic compounds, and this characterization is crucial to help convert coal-derived oils into alternative fuels.
This study showed that compared to conventional configurations, a reversed configuration involving a highly polar column in the first dimension and a non-polar one in the second enables the separation of oxygenates and hydrocarbons in one single run. In fact, the 2D contour plots obtained under these conditions exhibit a good resolution and a high space occupation. Nevertheless, in the future there is still an opportunity to separate the nitrogenates from the oxygenates for improved quantification. Further study is needed utilizing either sample preparation or online fractionation in a multi-technical analytical approach with multi-dimensional gas chromatography.
