초록

Oil shale은 kerogen을 함유한 퇴적암으로 대표적인 비재래 에너지자원으로 알려져 있다. 열분해 공정을 통하여 oil shale이 분해되면 oil, gas 및 coke를 생성하게 된다. 본 연구에서는 oil shale의 청정 전환기술을 개발하기 위하여 oil shale의 TGA 및 연속 열분해 연구를 수행하였다. Oil shale의 열분해 전환율에 대한 반응 온도 및 체류시간의 영향을 살펴보고 oil의 생성율을 살펴보았다. Oil shale의 열분해 전환율은 온도와 체류시간에 따라 증가하였으며 450 ~ 500 ℃, 체류시간 30 min의 조건에서 최대 oil 생산 수율을 나타내었다.

Oil shale is the sedimentary rock containing kerogen, which is one of the abundant unconventional fuel. In the pyrolysis process, oil, gas and coke are produced from the decomposition of oil shale. In this study, TGA and the continuous pyrolysis of oil shale have been investigated for the clean conversion of oil shale. Effects of reaction temperature and residence time on the pyrolysis conversion and oil production rate have been determined. Conversion of oil shale increases with increasing the reaction temperature and residence time. Optimum conditions for oil production were reaction temperature of 450 ~ 500 ℃ at the residence time of 30 min.

Keywords:Oil shale;Pyrolysis;TGA;Rotary tube furnace
