Abstract
In recent years, with increasing global warming and fossil fuel resource depletion, biodiesel has become a possible alternative to diesel fuel from the viewpoint of emission control. Biodiesel fuel is produced from renewable natural bio-sources and is easily combustible, and therefore various processes involved in biodiesel fuel production have been recently developed. In the present study, we produced biodiesel transportation fuel from fish waste oil using ozone treatments and evaluated its properties as an alternative to diesel fuel. Ozone treatment lowered the flash point of the produced fuel, resulting in easy combustibility. Quantitative changes in the amounts of fatty acids that form triglycerides and hydrocarbons in oil samples (untreated and ozone treated) were also shown. Total ion chromatograms produced from gas chromatography mass spectrometry (GC/MS) revealed that the fatty acid compositions of fish waste oil were decomposed to produce hydrocarbons. The ozone treated fish waste oil was considered a suitable alternative to diesel fuel from the viewpoint of fuel quality and exhaust gases.
