Abstract

The carbon precursor pitch from pyrolyzed fuel oil (PFO), by-product of Naphta cracking process (NCC), was prepared through heat and UV irradiation treatments with various concentrations of $AlCl_3$, which is a new pitch preparation method. The reformed pitches were characterized by measuring their elemental composition, chemical structure of components, molecular weight distribution, and softening point. The oxygen contents of reformed pitch increased as increasing $AlCl_3$ amounts on the other hand, the carbon and hydrogen contents were not nearly changed. UV irradiated reformed pitches were composed of more aromatic carbon compounds than that of using only heat-treatment without any UV irradiation. The addition of $AlCl_3$ catalyst was ineffective on the aromaticity of reformed pitches. The softening point of prepared pitches was in the range of $103.3{\sim}168.9^{\circ}C$. Also the yield of prepared pitch increased from 48% to 80% when 5 wt% of $AlCl_3$ was added during the heat and UV irradiation reforming. It is expected that the UV irradiation reforming method can be practical and helpful to produce high yields of pitches with diverse properties.

나프타 분해공정에서 부산물로 발생하는 분해연료오일을 이용하여 열처리 및 UV 조사 시 다양한 농도의 $AlCl_3$을 첨가하여 새로운 방법으로 탄소전구체 피치를 제조하였다. 개질된 피치는 원소 분석, 화학 구조, 분자량 분포 및 연화점을 분석하여 특성평가를 하였다. 개질된 피치의 산소 함량은 $AlCl_3$의 첨가량이 증가할수록 증가한 반면 그 탄소 및 수소 함량은 거의 변화하지 않았다. UV 조사 개질피치는 열 개질만 된 피치보다 더 많은 방향족 탄소화합물로 이루어져 있었다. $AlCl_3$ 촉매첨가는 개질된 피치의 방향족화도에 큰 영향을 미치지 않았다. 제조된 피치의 연화점은 $103.3{\sim}168.9^{\circ}C$ 범위를 나타내었다. 또한 5 wt%의 $AlCl_3$를 첨가하여 UV 조사 개질된 피치의 수율은 48%에서 80%로 증가하였다. 이것을 통하여 UV 조사 개질 방법은 다양한 특성을 갖는 고수율의 피치를 제조를 위한 실용적이고 유용한 방법으로 여겨진다.
