Detailed group-type characterization of plastic-waste pyrolysis oils : by comprehensive two-dimensional gas chromatography including linear, branched, and di-olefins Universiteit Gent
Plastic-waste pyrolysis oils contain large amounts of linear, branched, and di-olefinic compounds. This makes it not obvious to determine the detailed group-type composition in particular to the presence of substantial amounts of N-, S-, and O-containing heteroatomic compounds. The thorough evaluation of different column combinations for two-dimensional gas chromatography (GC × GC), i.e., non-polar × polar and polar × non-polar, revealed that ...
