Pyrolysis fuel oil (PFO) is the bottom fraction left after naphtha cracking process, and mainly composed of poly-condensed aromatic hydrocarbons. Although PFO has been widely investigated as a source for the synthesis of carbonaceous pitch, there are only limited studies on its structural features. Herein, structural characterization of PFO was performed using 1H & 13C nuclear magnetic resonance (NMR) spectroscopy. Specific classifications of chemical shifts in NMR spectra were carried out on the basis of Dickinson’s method. By combining data from NMR with molecular weight and elemental contents, average structural parameters were determined, and based on which, an average structural model of PFO was also proposed. |
