Abstract:
The pyrolysis of mixed plastic waste is a promising advanced recycling technology. The refinement of mixed plastic waste pyrolysis oils can be challenging because of the variable composition and properties of the oils. Methods are needed to characterize pyrolysis oils. Supercritical fluid chromatography (SFC) was investigated for the separation of pyrolysis oils. A method was devised to differentiate pyrolysis oils that are generated from polyethylene and polypropylene feedstocks using ultraviolet detection. SFC was also used with fraction collection to fractionate the oils for subsequent gas chromatography (GC) analysis. GC with mass spectrometric and vacuum ultraviolet spectroscopic detection were used.
