초록

바이오매스를 바이오오일로 전환시기키 위하여 오거형의 반응조를 설계, 제작하여 실험하였다. 10.2L의 반응조는 $550^{\circ}C$를 유지하며 Batch식으로 운영하였다. 돈분뇨 혼합물, 돈분 왕겨혼합물, 돈분 톱밥혼합물 등 세 가지 혼합물을 대상으로 주(主) 구성성분인 헤미셀루로즈, 리그닌, 셀루로즈, 단백질, 지질(脂質)등을 화학적으로 분석하였다. 실험결과에 의하면 전섬유소 (holocellulose = hemicellulose + cellulose), 리그닌(lignin)의 함유량이 클수록 바이오오일 생산량은 많았으나, 회분(ash)함량은 현저한 감소를 나타내었다. 본 연구에서는 다양한 바이오매스기질을 평가하였으며, 돈분과 왕겨의 상관성은 거의 나타나지 않았으나 돈분과 톱밥의 상관성은 매우 높게 나타났다.

Pyrolysis is recently used as one of alternative methods of animal waste treatment. In this study bio-oil was produced at $550^{\circ}C$ in an auger reactor through pyrolysis process. Two pig waste mixtures were used, pig feces mixed with rice husks and pig feces mixed with sawdust. The main compositions of hemicellulose, lignin, cellulose, protein, and fat were analyzed chemically. Based on the main composition results obtained, the contents of holocellulose (the sum of hemicellulose and cellulose) and lignin had a significant positive effect on bio-oil production, and there was a significant negative effect of ash content on bio-oil yield. The interactions between the different feedstocks were evaluated, and it was concluded that the interaction between pig feces and rice husks was minimal, whereas the interaction between pig feces and sawdust was significant.
