Abstract

Fossil fuel causes the greenhouse effect by emitting $CO_2$, and an estimated amount of oil deposits are also limited. Therefore, people have been interested in alternative energies. Vegetable oil which is one of the alternative energies is eco-friendly renewable energy source and has similar properties like diesel oil with high efficiency. Also, vegetable oil has been well recognized as one of solutions to reduce the greenhouse effect caused by $CO_2$release. In this study, we chose Waste vegetable oil(WVO) to solve the problems of high price of grain and lack of food. Impurities and sediments from WVO were removed by separation process using sieves of $15{\mu}m$pore size. Blending was performed in Homo-mixer by 5000 rpm for 10 min. We investigated viscosities and Iodine values in different compositions of WVO and diesel oil blends. Finally, we could find out blended oils have some possibility to be used in the diesel engine.

석유와 같은 화석연료는 $CO_2$의 방출로 인해 지구 온난화의 원인이 되고, 그 매장량 또한 한정되어 있다. 따라서 대체에너지에 관한 관심이 증대 되고 있고 이러한 대체 에너지 중 식물성 오일은 환경 친화적이며 재생산이 가능한 에너지원으로 기존의 고효율의 디젤유와 유사한 특성을 가지고 있다. 또한 식물성 오일은 $CO_2$방출에 의한 지구 온난화 문제를 줄일 수 있는 방법중의 하나로도 잘 알려져 있다. 본 연구에서는 곡물가격 상승과 식량자원 부족문제를 해결하기 위하여 폐식용유를 사용하였다. $15{\mu}m$구멍 입경을 갖는 시브를 사용하여 폐식용유(WVO)로부터 불순물과 침전물을 제거 한 후 Homo-mixer를 사용하여 5000rpm에서 10분간 디젤유와 혼합하였다. WVO와 디젤 블렌딩 용액의 요오드가(Iodine Value)와 점도 변화를 조사한 후 최종적으로 디젤 엔진에 적용결과 엔진구동에 가능성이 있음을 확인 하였다.
