ABSTRACT=<p>This study investigated the hydrodeoxygenation of palm oil by different oxide nanocatalysts of transition metals α -Fe<sub>2</sub>O<sub>3</sub>, NiO, and NiFe<sub>2</sub>O<sub>4</sub>, which were synthesized by hot injection. All nanomaterials were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, and dynamic light dispersion. The catalytic evaluation was performed in a Parr-type reactor at 350°C, 3.5 MPa of H<sub>2</sub> pressure, and 3 h of reaction. The liquid product obtained was analyzed by ultraviolet-visible light spectroscopy to identify the n-C<sub>16</sub> generated during the reaction. The activity in the deoxygenation of fatty acids to produce n-C<sub>16</sub> hydrocarbons has the following order: α-Fe<sub>2</sub>O<sub>3</sub> &lt; NiFe<sub>2</sub>O<sub>4</sub> &lt; NiO.</p>
