Abstract Pt/γ‐Al 2 O 3 catalysts were prepared by incipient wet impregnation and tested in hydrodeoxygenation reactions for conversion of oleic acid to n‐C 17 alkanes at optimal conditions. The high conversion of 96.5% to renewable biodiesel (RD) is justified with the characterization results, showing that the catalyst has good texture properties, presence of metallic Pt evidenced by 2 θ reflections and binding energies, as well as adequate dispersion of active phase and nanoparticle size. 20% and 40% mixtures of RD with diesel were used. At full load a slight decrease in potency was observed when using RD mixtures and comparing them with petrodiesel; fortunately, the RD mixtures showed significant reductions in air pollutants, RD40 achieved reductions greater than 22% for CO, HC, and near 43% in emissions of smoke when compared to diesel.
