Abstract

볏짚은 국내에서 유용한 재생 가능한 바이오매스이다. 유동층과 char 분리 장치가 구비된 벤치 규모 급속 열분해 장치와 제올라이트 촉매를 이용하여 볏짚으로부터 바이오 오일의 생산에 대한 실험을 수행하였다. 본 연구는 제올라이트 촉매의 첨가에 따른 볏짚의 열분해 생성물의 분포와 바이오 오일의 화학적 구성을 알아보기 위한 것이다. 볏짚의 촉매 열분해 결과 무촉매 열분해에 비해 기체, char 성분은 증가하고 액체 성분은 감소하였다. 또한, 오일 중 수분이 탈산소의 영향으로 증대된 결과를 가져왔다. 촉매 열분해의 경우 오일 성분 중의 aromatics 성분이 증대되었고 발열량이 증가하였다.

Rice straw is one of the main renewable energy sources in Korea. Bio-oil is produced from rice straw with a bench-scale equipment mainly with a fluidized bed, a char removal system and zeolite catalyst. It was investigated how the zeolite catalyst affected the production of bio-oil and chemical composition of bio-oil. Compared with non catalytic pyrolysis, the catalytic pyrolysis increased the amount of gas and char but decreased the amount of oil. The water content in bio-oil increased due to deoxygenation. The aromatic compound and heating value was increased when catalytic pyrolysis was applied.
