Abstract: In this paper we analyze differences in fatty acid methyl ester (FAME: methyl palmitate, methyl octanoate), fatty acid ethyl ester (FAEE: ethyl laurate), and triglyceride (TG – tricaprylin) hydrodeoxygenation (HDO). These differences are attributed to chemical nature of FAME, FAEE, and TG, and different reaction rates of the initial compounds. The HDO experiments were carried out in continuous flow fixed bed reactor at 250–330 °C and 3 MPa. Ni2P supported on SiO2, SBA-15, or Al2O3 were used as catalysts. The rates of O removal for FAME, FAEE, and TG are the same for the catalyst with high acidity (Ni2P/Al2O3), but different for the catalyst with low acidity (Ni2P/SiO2). It turned out that the rate of fatty acid conversion is significantly higher at the same conditions compared to the initial esters. Thus, it was concluded that TG rapidly transforms to fatty acid and there is almost no influence of catalyst acidity on the TG HDO rate, i.e., no synergetic effect of metal and acid sites can be obtained for TG HDO.
