Ni-based catalysts are easy deactivated in bio-lipids deoxygenation due to metal aggregation and Ni leaching. They also suffer from the hydrocracking of Csingle bondC bonds due to strong acidity at high reaction temperature (≥ 300 ℃). Herein, a series of Ni/CeO2-Al2O3catalysts with different Ce/Al ratio were prepared by one-pot sol-gel method. The characteristic results showed that an appropriate addition of Ce both increase the catalytic activity and stability in bio-lipids deoxygenation. The oxygen vacancies formed by Ce introduction weaken the strong interaction of Ni-Al, thus improving Ni sites dispersion. Additional, Ce-addition in NiCeAl system increases weak and medium acidity and decreases strong acidity, preventing the Csingle bondC bond cleavage of hydrocarbon. As the result, the Ni/CeAl-3.0 catalyst afforded a 97.1 % n-C17yield at 99.9 % MO conversion under 2.5 MPa H2at 300 ℃ for 6 h. Minor C15-16alkanes (<2 %) was detected in liquid products indicating that excellent resistance to Csingle bondC bonds hydrocracking was obtained. Notably, the Ni/CeAl-3.0 still maintained high performance after sixth consecutive runs (90.6 % MO conversion and 89.8 % n-C17yield). After simple regeneration, n-C17yield was recovered to 95 %. Furthermore, non-edible bio-lipids (JO and WCO) can be converted to C13-18alkanes with 95.2 % and 93.8 % yields, respectively.
