The mesoporous Ni 20 /Al-KIT-6 (denoted as N 20 A x K) catalysts with different Al content (1–9 wt%) were prepared, metal Ni and KIT-6 modified by Al were used as active component and support, respectively. The physicochemical properties of the prepared N 20 A x K catalysts were characterized by H 2 -TPR, XRD, BET, TEM, and H 2 -TPD. The catalytic hydrodeoxygenation(HDO) performance of N 20 A x K catalysts was evaluated by ethyl acetate catalytic HDO. The results show that the catalytic HDO performance of the prepared N 20 A x K catalysts is related to the adsorption and activation performance for H 2  molecules, as well as the dispersion of matal Ni active components. N 20 A 5 K catalyst shows the best H 2  adsorption property and Ni dispersion. N 20 A 5 K catalyst presents superior catalytic HDO performance. At 300 °C and atmospheric pressure, the conversion of ethyl acetate and ethane selectivity of N 20 A 5 K catalyst are 99.3 % and 97.4 %, respectively. Besides, the N 20 A 5 K catalyst exhibits good stability.
