Influence of high thermal treatment on aromatic portion of pyrolysis fuel oil-derived isotropic pitches |
| 초록 |
Pyrolysis fuel oil (PFO) was initially pretreated by oxidation and then treated at 360 °C for various lengths of time. The influence of heat treatment time on the preparation of PFO-derived pitches was analyzed by FT-IR, NMR, electrical resistivity, and carbon yield. FT-IR spectra demonstrated that the intensities of the aromatic C–H bonds at 1600 and 3042 cm-1 of the PFO-derived pitches significantly increased and the intensity of the stretching vibration of the C–H bond at 2910 cm-1 decreased with an increase in heat treatment time. NMR analysis demonstrated that the intensity of the aromatic portion (7-11 ppm) of the PFO-derived pitches increased with an increase in heat treatment time. The increase of the aromatic portion in the PFO-derived pitches caused the electrical resistivity to decrease and the carbon yield to increase. |
