Candida Antarctica Lipase를 이용한 폐유의 바이오디젤의 제조

Abstract

Enzymatic biodiesel using lipase Novozyme-435 instead of using chemical catalyst was studied in this paper for cost reduction, increase of production efficiency and environment friendly product in this paper. In this paper the standard of biodiesel quality was met by using enzyme. The optimal reaction condition of methanol/waste oil molar ratio was 3, which 1 mol of methanol was injected at initial reaction. Then, each of 1 mol of methanol was injected at 4 hours of interval. Other reaction condition was like as follows : Reaction temperature, reaction time, agitation speed and amount of lipase were 55oC, 24 hours, 400 rpm, and 6wt%, respectively.
