Abstract

The low temperature pyrolysis of ABS resin has been carried out in a batch reactor under the atmospheric pressure. The effect of the reaction temperature on the yield of pyrolytic oils has been determined in the present study. 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 Ministry of Knowledge Economy. The conversion reaches 80% after 60 min at $500^{\circ}C$ in the pyrolysis of ABS resin. The amount of the final product was ranked as gas heavy oil > gasoline > gas oil > kerosen based on the yield. The yields of heavy oil and gas oil increase with an increase in the reaction time and temperature.

ABS 수지의 반응온도 및 반응시간에 따른 저온 열분해를 연구하기 위하여 ABS 수지의 저온열분해를 회분식 반응기를 이용하여 상압하에서 $425{\sim}500^{\circ}C$ 영역에서 수행하였다. 열분해 시간은 20~80분까지 하였고 열분해로 생성된 성분은 지식경제부에서 고시한 증류성상온도에 따라 가스, 가솔린, 등유, 경유, 중유로 분류하였다. ABS 수지의 열분해에서 80% 이상의 전환율을 얻기 위해서는 반응온도 $500^{\circ}C$ 이상에서 반응시간 60분 이상을 유지하여야 한다. 최종적으로 생성된 분해유는 가스 중유 > 가솔린 > 경유 > 등유 순으로 나타났으며, 온도와 반응시간이 증가함에 따라 중유 및 경유 성분이 늘어났다.
