The development of renewable diesel fuel from the deoxygenation of non-edible oil is an alternative to non-renewable fuels. Herein, the evaluation of catalytic deoxygenation of waste cooking oil (WCO) over supported Ni-based catalysts was investigated. A series of Ni-based catalysts supported on activated carbon (AC), reduced graphene oxide (rGO), and beta zeolite (Zeo) were prepared via the wet-impregnation method and later carbonised under N₂ flow at 550 °C for 4 h. Addition of Ni to AC improves the good physicochemical properties of the catalyst, owing to the high number of acid-base sites, high surface area, smaller crystallite size, and high pore volume of the catalyst. From the catalytic results, Ni₂₀/AC was the most active catalyst by giving 90% hydrocarbon yield and 89% selectivity towards n-(C₁₅ + C₁₇) under H₂-free and solvent-free conditions for 3 h at 350 °C and 300 rpm. Furthermore, it was stable up to the fourth cycle with consistent hydrocarbon yield (85–87%) and 66–77% selectively towards n-(C₁₅ + C₁₇). Overall, Ni₂₀/AC shows highly promising catalytic performance due to its good physiochemical properties and high catalyst stability.

从非食用油的脱氧中开发可再生柴油燃料是不可再生燃料的替代品。在此，研究了在负载的 Ni 基催化剂上对废食用油 (WCO) 进行催化脱氧的评估。通过湿浸法制备了一系列负载在活性炭 (AC)、还原氧化石墨烯 (rGO) 和 β 沸石 (Zeo) 上的 Ni 基催化剂，然后在 N ₂流下在 550 °C下碳化4 h . 由于催化剂具有大量的酸碱位点、高表面积、较小的晶粒尺寸和高孔体积，在活性炭中添加镍改善了催化剂的良好物理化学性质。从催化结果来看，Ni ₂₀/AC 是活性最高的催化剂，在 350°C 和 300 rpm下，在无 H ₂和无溶剂条件下持续 3 小时，对n -(C ₁₅  + C ₁₇ ) 的选择性为 90% 和 89% 。此外，它一直稳定到第四个循环，具有一致的烃产率（85-87%）和 66-77% 选择性地朝向n -（C ₁₅  + C ₁₇）。总体而言，Ni ₂₀ /AC 由于其良好的理化性质和高催化剂稳定性而显示出非常有前景的催化性能。
