Abstract

The low-temperature pyrolysis of ABS, polyethylene (PE) and an ABS-polyethylene (ABS-PE) mixture was conducted in a batch reactor at $450^{\circ}C$. The conversion and the product yield were measured as a function of the reaction time with a variation of the mixture composition. The oil products formed during pyrolysis were classified into gas, gasoline, kerosene, gas oil and heavy oil according to the petroleum product quality standard of the Ministry of Knowledge Economy. The pyrolysis conversion increases with an increase in the content of PE. The yield of the pyrolytic products was ranked as heavy oil>gas>gasoline>gas oil>kerosene as the content of PE in the mixture increases.

ABS와 폴리에틸렌(Polyethylene, PE) 및 ABS-PE 혼합물의 저온열분해를 회분식 반응기를 이용하여 상압 및 $450^{\circ}C$에서 실행하였다. 열분해 시간은 20~80분까지 하였고 열분해로 생성된 성분은 지식경제부에서 고시한 증류성상온도에 따라 가스, 가솔린, 등유, 경유, 중유로 분류하였다. ABS와 PE의 혼합 폐플라스틱의 열분해 전환율은 PE의 함량이 증가할수록 증가하는 것으로 나타났다. 열분해생성물의 수율은 PE의 함량이 높을수록 중유 > 가스 > 가솔린 > 경유 > 등유 순으로 회수되었다.
