Abstract
This paper deals with the hydroprocessing of Fish Oil (FO) as a source to produce biofuel. The hydrotreating experiments were performed at 380�C and 50bar pressure over the CoMo/Al2O3 and CoMoRe/Al2O3 catalysts. Through hydrogenation of double bonds and carboxyl groups of Fatty Acids (FAs), accompanied by secondary hydrocracking and isomerization reactions, there results a mixture of normal & isoparaffin with 13-22 carbon atoms per molecule with physicochemical characteristics similar to diesel fuel. The hydrotreatment of Straight Run Gas Oil (SRGO) mixed with 5% and 10% (FO) was also studied. The research focuses on the influence of the SRGO-FO ratio and of the catalyst type on the yields and the physiochemical properties of the obtained biofuel. The results show that the hydrotreatment of FO and of SRGO-FO mixtures is an alternative for biofuel production with characteristics similar to diesel fuel.
