摘要：

Ni10/γ-Al2O3, Ni5-Fe5/γ-Al2O3 and Fe10/γ-Al2O3 catalysts were prepared by impregnation method. The hydrodeoxygenation (HDO) performance of the prepared catalysts were evaluated by methyl laurate. Physicochemical properties of the studied catalysts were tested by H2-TPR, XRD and H2-TPD. The NiFe alloy was confirmed in bimetallic catalyst with XRD, which is helpful to improve the catalytic HDO performance of the corresponding catalyst. The synergistic effect between Ni and Fe is also elucidated. The introduction of Fe species has a significant effect on the HDO performance and product selectivity of the Ni-based catalyst. The catalytic performance of the bimetallic catalyst is better than that of the monocomponent metal catalyst at low reaction temperature. The conversion of methyl laurate is up to 86.79% and the selectivity of alkane compounds can exceed 90% over the Ni5-Fe5/γ-Al2O3 catalyst, when the reaction temperature is 340℃. © 2021, Solar Energy Periodical Office Co., Ltd.
