초록

열분해 온도 및 열분해 시간이 HDPE의 열분해에 미치는 영향을 해석하였다. HDPE 열분해의 시작온도와 활성화에너지는 가열속도가 증가함에 따라 증가하였다. 전환율과 액체수율은 열분해 온도와 시간이 증가함에 따라 계속 증가하였고, 특히 450 ℃에서 열분해 시간에 매우 민감하게 변하였다. 전환율에 있어 열분해 온도가 열분해 시간보다 더 큰 영향을 주었다. 열분해 과정에서 생성된 각각의 액체 성분을 한국석유품질검사소 석유제품 품질기준에 기초하여 증류온도에 따라 가솔린, 등유, 경유, 왁스로 분류하여 본 결과, 450 ℃에서는 경유 > 왁스 > 등유 > 가솔린 순이었고, 475 ℃와 500 ℃에서는 왁스 > 경유 > 등유 > 가솔린 순이었다.

Pyrolysis of high density polyethylene(HDPE) was carried out to find the effects of temperature and time on the pyrolysis. The starting temperature and activation energy of HDPE pyrolysis increased with increasing heating rate. In general, conversion and liquid yield continuously increased with pyrolysis temperature and pyrolysis time. This tendency is very sensitive with pyrolysis time, especially at 450 ℃. Pyrolysis temperature has more influence on the conversion than pyrolysis time. Each liquid product formed during pyrolysis was classified into gasoline, kerosene, light oil and wax according to the distillation temperature based on the petroleum product quality standard of Korea Petroleum Quality Inspection Institute. As a result, the amount of liquid products produced during HDPE pyrolysis at 450 ℃ was in the order of light oil > wax > kerosene > gasoline, and at 475 ℃ and 500 ℃, it was wax > light oil > kerosene > gasoline.
