The influence of the Si/Al ratio of ZSM-5 on 10 wt% Ni/ZSM-5.SAPO-11 catalysts were investigated through the palm oil hydrodeoxygenation (HDO) process, based on the product selectivity of alternative jet fuel. This study utilizes a 1 L batch reactor at 60 bar and 350 °C for palm oil hydrodeoxygenation over 10 wt% Ni/ZSM-5.SAPO-11 catalysts. Si/Al ratio of 50 produces a 10 wt% Ni/ZSM-5.SAPO-11 catalyst with the optimum physicochemical properties for palm oil hydrodeoxygenation. TGA/DTG analysis of the spent catalyst shows that the catalyst has good thermal and catalyst stability with minor carbon deposition. GC/MS analysis also demonstrated a 100 % palm oil conversion to alternative jet fuel. The highest jet fuel yield of 51 % was attained with a Si/Al ratio of 50. The physicochemical properties of alternative jet fuel samples were measured to ensure that the conventional fuel standard limits were appropriately followed. These results indicated that such types of bifunctional Ni-based catalysts have the potential to be used in the conversion of triglycerides to alternative jet fuel.

双功能沸石混合物负载 Ni 催化剂上棕榈油加氢脱氧生产喷气燃料：Si/Al 比的影响


基于替代喷气燃料的产品选择性，通过棕榈油加氢脱氧 (HDO) 工艺研究了 ZSM-5 的 Si/Al 比对 10 wt% Ni/ZSM-5.SAPO-11 催化剂的影响。本研究利用 1 L 间歇式反应器在 60 bar 和 350 °C 下通过 10 wt% Ni/ZSM-5.SAPO-11 催化剂进行棕榈油加氢脱氧。 Si/Al 比为 50 时可生成 10 wt% Ni/ZSM-5.SAPO-11 催化剂，该催化剂具有棕榈油加氢脱氧的最佳物理化学性质。对废催化剂的TGA/DTG分析表明，该催化剂具有良好的热稳定性和催化剂稳定性，积炭量少。 GC/MS 分析还表明，棕榈油 100% 转化为替代航空燃料。当硅/铝比为 50 时，喷气燃料产率最高可达 51%。对替代喷气燃料样品的物理化学性质进行了测量，以确保适当遵循传统燃料标准限值。这些结果表明，此类双功能镍基催化剂有潜力用于将甘油三酯转化为替代喷气燃料。
