Abstract

As it carry out RPS(Renewable Portfolio Standards), power producers are using the power bio-fuel oil to meet their RPS quota. In this study, we test the quality characteristics of raw materials for power bio-fuel oil and the property changes of power bio-fuel oil by the kind of feedstocks. The power bio-fuel oil and feedstocks were analyzed for item of quality standard such as acid number, viscosity and metal contents. And it was analyzed for composition distribution by FT-IT and HPLC. Such as low priced palm oil series has high acid number and ash contents due to high free-fatty acid and metal contents. And by-product of biodiesel have a tendency of high viscosity. The fuel properties of power bio-fuel oil, such as viscosity, acid number and metal contents are correlated with the constituent and the mixing ratio of the feedstocks.

신재생에너지 공급 의무화제도(Renewable Portfolio Standard(RPS))가 시행됨에 따라, 발전 사업자들은 의무공급량 이행을 위해 발전용 바이오중유를 사용하고 있다. 본 연구에서는 발전용 바이오중유의 원료물질별 물성과 원료 조성에 따른 발전용 바이오중유의 품질특성을 알아보았다. 발전용 바이오중유와 원료유지의 연료특성은 전산가, 동점도, 금속분 등 고시 상 품질기준 항목을 분석하였으며, 적외선 분광광도계와 고성능 액체크로마토그래피를 이용하여 조성분포를 분석하였다. 팜유계열의 저가의 고산가 유지는 유리지방산 함량이 높아 전산가가 높고, 금속분에 의한 회분함량이 높았으며, 바이오디젤 공정부산물은 점도가 높았다. 동점도, 전산가, 금속분과 같은 발전용 바이오중유의 연료특성은 원료물질 의 조성 및 혼합비와 관련이 깊다.
