Three types of zeolites (Meso-Y, SAPO-34, and HY) loaded with nickel were used to convert waste cooking oil to jet biofuel. Mesoporous zeolite Y exhibited a high jet range alkane selectivity of 53% and a proper jet range aromatic hydrocarbon selectivity of 13.4% in liquid fuel products. Reaction temperature was optimized to produce quality jet biofuel. Zeolite Meso-Y exhibited a high jet range alkane yield of 40.5% and a low jet range aromatic hydrocarbon yield of 11.3% from waste cooking oil at 400°C. The reaction pathway for converting waste cooking oil to jet biofuel was proposed. Experimental results showed that waste cooking oil mainly deoxygenated to heptadecane (C17H36) and pentadecane (C15H30) through the decarbonylation pathway for the first 3h. Long chain alkanes cracked into jet range alkanes (C8-C16). Cycloalkanes and aromatic hydrocarbons were produced through cyclization and dehydrogenation pathways.
三种沸石（中孔 Y 型、SAPO-34 和 HY）负载镍被用于将废食用油转化为喷气式生物燃料。中孔 Y 型沸石在液体燃料产物中表现出 53%的高喷气式烷烃选择性和 13.4%的合适喷气式芳烃选择性。反应温度被优化以生产高质量的喷气式生物燃料。在 400°C 时，沸石 Meso-Y 从废食用油中表现出 40.5%的高喷气式烷烃收率和 11.3%的低喷气式芳烃收率。提出了将废食用油转化为喷气式生物燃料的反应途径。实验结果表明，废食用油主要通过脱羰途径在最初的 3 小时内脱氧生成十七烷（C17H36）和十五烷（C15H30）。长链烷烃裂化成喷气式烷烃（C8-C16）。环烷烃和芳烃通过环化和脱氢途径生成。
