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