Pyrolysis fuel oil (PFO) is reformed by heat and UV irradiation treatment with various concentrations of AlCl3 to investigate new pitch reforming method. UV irradiated reformed pitches are composed of more aromatic carbon compounds than heat-reformed pitches. However, addition of AlCl3 is not effective for increasing aromaticity of reformed pitches. The softening point values of prepared pitches are in the range of 103.3-168.9 ℃. The yield of prepared pitch also increased from 40% to 80%, when 5 wt% of AlCl3 is added during heat and UV irradiation reforming. It is expected that pitch reforming method using UV irradiation is novel, practical, and helpful to produce high yield of pitches. |
