Abstract: Different γ-Al2O3 supports are prepared by changing the addition amount of peptizator nitric acid in the process of support extrusion.NiMo/γ-Al2O3 (15% Ni and 5% Mo) is prepared by excess impregnation method.The supports and catalysts both are characterized by means of BET,XRD and SEM.The effect of supports on the catalytic performance of catalysts is investigated by carrying out evaluation on catalytic performance in the hydrogenation of fatty acid methyl ester (FAME).Evaluation results reveal that when the addition amount of peptizator nitric acid is 7.5% of the mass of pseudo-boehmite,reaction pressure is 2.9 MPa,temperature is 355℃ and LHSV is 2.0 h-1,the corresponding NiMo/γ-Al2O3 catalyst show better hydrodeoxygenation performances with the conversion of FAME reaching 92.5% and the selectivity of n-alkanes (C15-C18) in liquid phase products being 71.7%.
