Abstract:

The crude fish oil from the waste parts of marine fish is considered to be alternative source of abundant and low-cost feedstock for biodiesel production. Fish oil extracted from the waste parts of marine fish is rich in polyunsaturated fatty acids. Thus, the biodiesel produced from marine fish oil may have lower oxidative stability. To better understand how to improve the oxidative stability of marine fish-oil biodiesel, the influence of oxidative variables including antioxidant addition, operating temperature and storage time on the fuel characteristics of this biodiesel is investigated in this study. The experimental results show that the addition of antioxidant significantly retards the deterioration over time of the fuel characteristics of the marine fish-oil biodiesel. Operating temperature was found to be a dominant factor in the deterioration of the fuel characteristics of this biodiesel. The marine fish-oil biodiesel sample to which no antioxidant has been added and which has been stored at a higher temperature appears to have the highest deterioration rate of methyl ester content and greatest rate of increase in acid value, kinematic viscosity, and carbon residue among the four tested biodiesel samples. Moreover, the addition of a combination of two antioxidants was found to have a slightly greater effect in reducing the deterioration rate of the fuel characteristics of this biodiesel than the addition of a single antioxidant alone. However, the addition of antioxidant to the fish-oil biodiesel results in an increase in kinematic viscosity and carbon residue at the beginning of the storage period.
