Zhu, Yanli published the artcileHydrodeoxygenation of Octanoic Acid over Supported Ni and Mo Catalysts: Effect of Ni/Mo Ratio and Catalyst Recycling, Formula: C8H18O, the main research area is octanoic acid hydrodeoxygenation nickel molybdenum catalyst support recycling.
Hydrodeoxygenation of octanoic acid over supported NiMo bimetallic catalysts was investigated as a representative of carboxylic acid compounds in bio-oils. A series of MCM-41 supported Ni and Mo bimetal catalysts were prepared with the wetness impregnation method. The microstructural and physicochem. properties of the fresh and recovered bimetal catalysts were characterized by various methods such as X-ray diffraction (XRD), SEM (SEM) and XPS, etc.. The results show that the bulk NiO particles were well-uniformly dispersed on the surface of the bimetal catalyst, and Mo4+ was founded as the main valence of Mo inside solid. Under the optimal conditions, i. e. the reaction temperature of 270°C, reaction pressure of 3 MPa, and reaction time of 7 h, the 3Ni7Mo/MCM-41 sample exhibits selectivity to octane 72.6% with a high conversion of octanoic acid 96.1%. Only a slight decrease in catalytic activity was observed after reused for three times. Moreover, the recovered sample was easily regenerated only with simple calcination and deoxidization, but has the similar microstructure compared with the fresh one.
