Pyrolysis fuel oil (PFO) is a petroleum residue oil obtained from naphtha cracking centers in the petroleum refining process. It has received much attention due to such advantages as its high aromaticity, low sulfur content, low toluene-insoluble content, and low cost. PFO is especially suitable for the manufacture of pitch, which is a precursor of several carbon materials. PFO can be converted into pitch through heat reaction treatment. The conditions of the PFO heat reaction play a very important role, as they can influence the chemical structures of the produced pitch [8-10]. Currently, researchers are studying pitch extraction from PFO using various methods and heat conditions. In this study, PFO was pretreated by oxidation with H2O2 to increase the carbon yield, and then heat-treated for various lengths of time to further increase the carbon yield. The obtained pitches were characterized by FT-IR, H-NMR, carbon yield and electrical conductivity. |
