Comparison of Oil Shale Liquids with High Sulfur content using Multidimensional Gas Chromatography

摘要

1. Shale oil is exceedingly complex and its composition varies significantly, depending on the source and preparation conditions. 2. GC×GC provides substantially more efficient component separation than 1D GC and facilitates distinct hydrocarbon class separation. 3. This allows for superior identification of relatively minor (polar) components in the presence of high concentration (non-polar) compounds. 4. For S-compounds, GCxGC-FPD enables class separation of thiophenes, benzothiophenes, dibenzothiophenes. 5. Reliable quantitation of these S-classes can be achieved using a Σ(peak area)~(0.5) metric.
