Abstract

The effect of additives in the synthesis of biodiesel fuel using supercritical methanol was studied in order to examine the possibility of application of spent vegetable oil as a raw material, which has high contents of water or free fatty acid. The experiments were performed by varying the contents of water, free fatty acid or antioxidants respectively in a batch reactor. The contents of fatty acid methyl ester was analyzed by a gas chromatography. As the water contents increased, the contents of fatty acid methyl ester decreased, however, the decrease was very little compared with the alkaline and acid catalyst. The effect of the contents of free fatty acid, vitamin E, and ${\beta}$-carotene was negligible.

수분이나 유리지방산 함량이 높은 폐식용유의 적용 가능성을 알아보기 위하여 초임계메탄올을 이용한 바이오디젤 연료의 합성에서 첨가물이 미치는 영향에 대해 실험하였다. 회분식 반응기를 이용하여 물, 유리지방산, 항산화물질의 함량을 달리하여 전이에스테르화반응을 진행하였고, 기체크로마토그래피를 이용해 시료에 포함된 지방산메틸에스테르의 양을 측정하였다. 수분이 증가함에 따라 생성되는 지방산메틸에스테르의 함량이 약간 감소했으나 염기촉매나 산촉매에 비해서는 그 폭이 아주 작았다. 유리지방산, 비타민 E, ${\beta}$-카로틴의 함량 변화에 따른 영향은 거의 없었다.
