Ni-based catalysts supported on γ-Al₂O₃ and SiO₂ were prepared by impregnation. Catalyst characterization was performed using XRD, NH₃-TPD, H₂-TPR and chemisorption. Effects of supports on catalytic performance were tested using the hydrodeoxygenation (HDO) of phenolic compounds as a model reaction. Experiment result shows that single phenolic compounds can be converted via HDO reaction over Ni/SiO₂ and Ni/γ-Al₂O₃ catalysts at 300 °C. The hydrocarbon yields are in the range of 60–90%. The effect of supports on the reaction mechanism was also explored. It is found that hydrogenation of the aromatic ring preferentially occurs over Ni/SiO₂ catalyst while the cleavage of C_ARO bond preferentially occurs over Ni/γ-Al₂O₃ catalyst in the HDO of phenol. Compared to Ni/γ-Al₂O₃ catalyst, Ni/SiO₂ catalyst exhibits better repeatability and higher catalytic activity for hydrocarbon yield when mixed phenolic compounds were used as feedstock in the HDO reaction, and the carbon deposited on the surface of Ni/SiO₂ catalyst is lower.

Ni基催化剂负载在γ-Al系₂ ö ₃和SiO ₂，通过化学浸渍制备。使用XRD，NH ₃ -TPD，H ₂ -TPR和化学吸附进行催化剂表征。使用酚类化合物的加氢脱氧（HDO）作为模型反应，测试了载体对催化性能的影响。实验结果表明，单酚类化合物可以通过HDO反应在Ni /二氧化硅被转换₂和Ni /γ-Al系₂ ö ₃催化剂在300°C下。碳氢化合物的产率在60-90％的范围内。还探讨了载体对反应机理的影响。据发现，芳族环的氢化优先发生在Ni /二氧化硅₂催化剂而C的裂解_AR O键优先发生在Ni /γ-Al系₂ ö ₃在苯酚的HDO催化剂。与Ni相比/γ-Al系₂ ö ₃催化剂，镍/二氧化硅₂时混合酚类化合物被用作原料的HDO反应，并沉积Ni的表面上的碳催化剂具有更好的可重复性和更高的催化活性为烃产量/ SiO ₂催化剂较低。
