초록
오거 반응기를 이용하여 해조류 바이오매스인 다시마로부터 열분해 오일 제조 실험을 수행하였으며, 열분해 오일의 물리화학적 특성을 살펴보았다. 주요 공정 변수인 열분해 온도 및 오거 컨베이어 속도의 최적 조건은 각각 412 ℃, 20 rpm이었으며, 이 때 열분해 오일의 최대 수율은 32 wt%이었다. 낮은 탄소 함량 및 높은 산소 함량으로 인해, 다시마 유래 열분해 오일의 발열량(23.6 MJ kg-1)은 기존 화석연료의 약 60% 이었다. 열분해 오일의 GC/MS 분석 결과, 1,4-Anhydro-d-galactitol, dianhydromannitol, 1-hydroxy 2-propanone, isosorbide 등이 주요 화합물로 확인되었다. 촤는 탄소 함량이 낮고 산소함량이 높아 발열량(13.0 MJ kg-1)이 낮으며 다량의 무기 성분 및 황을 포함하고 있는 것으로 확인되었다.
Pyrolysis of Saccharina japonica in an Auger reactor was conducted by varying the temperature and the auger speed and then physicochemical properties of the S. japonica-derived pyrolysis oil were analyzed. The maximum yield of S. japonica-derived pyrolysis oil (32 wt%) was obtained at a pyrolysis temperature of 412 ℃ and an auger speed of 20 rpm. Due to low carbon content and high oxygen content in the pyrolysis oil, the higher heating value of S. japonica-derived pyrolysis oil was 23.6 MJ kg-1, which was about 60% that of conventional hydrocarbon fuels. By GC/MS analysis, 1,4-Anhydro-d-galactitol, dianhydromannitol, 1-hydroxy 2-propanone and isosorbide were identified as the main chemical compounds of S. japonicaderived pyrolysis oil. The bio-char has low higher heating value (13.0 MJ kg-1) due to low carbon content and high oxygen content and contains a large amount of inorganic components and sulfur.
