Abstract
가열속도 및 체류시간의 변화에 따른 PVC의 열분해 특성에 관한 연구를 TG, GC-MS 및 FT-IR을 이용하여 수행하였다. 가열속도가 감소할수록 열분해 생성 오일의 수율 및 중질류의 함유량은 증가하였으며 가열속도가 증가할수록 열분해로부터의 BTX 및 저분자량 물질의 수율이 증가하였다. 회수된 오일의 주요 구성 성분은 BTX, indane, indene 그리고 나프탈렌 및 antracene 등이었다. 체류시간이 증가할수록 Diels-Alder반응에 의한 에틸렌 및 부타디엔 등과 같은 기상 생성물의 재중합으로 인하여 오일의 수율이 증가하였다.
The characteristics of poly(vinyl chloride)(PVC) pyrolysis has been studied by using thermogravimetry(TG), gas chromatograph-mass spectrometry(GC-MS) and fourier transform infrared spectroscope(FT-IR) under various heating rates and residence times. The yield of pyrolytic oil and the content of heavy oil increases as the heating rate decreases. As the heating rate increases, an increasing tendency of the yield of BTX and low molecular weight materials is observed. The recovered oil products are mainly composed of BTX, indane, indene, naphthalene and anthracene. As the residence time increases, the yield of oil increases because gas phase products such as ethylene and butadiene are combined by the Diels-Alder reaction.
