Abstract:
Waste plastic pyrolysis oils (WPPOs) are complex, variable mixtures. Unsaturation governs stability, upgrading severity, and the quality of fuel-range cuts. Reliable, transferable olefin quantification across whole oils and distillates is therefore essential. Here is presented an advancement over our prior gasoline-range method, extending precise quantification to jet-range fractions and progressing toward diesel-range application. The approach couples comprehensive two-dimensional gas chromatography with flame ionization detection (GC×GC–FID) with targeted derivatization to reposition olefins in the GC×GC space, enabling robust indirect quantification with carbon-number- and class-resolved outputs amid paraffins, naphthenes, and aromatics.
