Pt/γ-Al₂O₃ catalysts were prepared by incipient wet impregnation and tested in hydrodeoxygenation reactions for conversion of oleic acid to n-C₁₇ 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 2θ 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.

Pt/γ-Al2O3催化剂对油酸加氢脱氧得到的生物燃料柴油机性能和大气排放评价

Pt/γ-Al ₂ O ₃催化剂是通过初始湿浸渍法制备的，并在加氢脱氧反应中进行了测试，以在最佳条件下将油酸转化为 nC ₁₇烷烃。表征结果证明了 96.5% 的可再生生物柴油 (RD) 的高转化率，表明该催化剂具有良好的织构特性，2 θ证明了金属 Pt 的存在反射和结合能，以及活性相和纳米颗粒尺寸的充分分散。使用了 20% 和 40% 的 RD 与柴油的混合物。当使用 RD 混合物并将它们与石油柴油进行比较时，在满负荷下观察到效力略有下降；幸运的是，RD 混合物显着减少了空气污染物，与柴油相比，RD40 的 CO、HC 减少了 22% 以上，烟雾排放减少了近 43%。
