Influence of bimetallic characteristics on the performance of MoCoP and MoFeP catalysts for methyl laurate hydrodeoxygenation

To study the influence of bimetallic characteristics on activity and selectivity, SiO2-supported monometallic (CoP, FeP and MoP) and bimetallic (MoxCo1-xP and MoxFe1-xP (x = 0.5)) phosphides were investigated for the deoxygenation of methyl laurate to C11-C12 hydrocarbons. Here, we aimed to modulate...

Here, we aimed to modulate the catalytic properties using different metal compositions with equimolar amounts of total metal phosphide. The catalysts were characterized by X-ray diffraction, N2 adsorption-desorption at -196 °C, transmission electron microscopy, CO chemisorption, NH3 temperature-programmed desorption and X-ray photoelectron spectroscopy; the conversion of methyl laurate, selectivity for hydrocarbons and C11/C12 ratio were related to the composition and physicochemical properties of the catalysts. The conversion (maximum of 85 % for MoP and minimum of 8 % for FeP) is mainly influenced by phosphide dispersion, which, in turn, is associated with acidity, and the same trend was found for both parameters (MoP/SiO2> MoCoP/SiO2 > MoFeP/SiO2 > FeP/SiO2 > CoP/SiO2). The yield of hydrocarbon formation follows the trend MoP/SiO2 > MoCoP/SiO2 > CoP/SiO2 > MoFeP/SiO2 > FeP/SiO2, with synergy between Mo and Co in the MoCoP catalyst. The C11/C12 ratio is influenced by the metal phosphide nature; the results indicate that Mo-based catalysts favor a hydrogenation (dehydration) pathway (C12 selectivity, 91 % in MoP/SiO2) and that Co-based catalysts favor oxygen elimination by decarbonylation/decarboxylation (C11 selectivity 75 % in CoP/SiO2). The activity results show synergy between Mo and Co in bimetallic phosphides by a kind of interaction that yields an enhancement in the catalytic activity of the MoCoP/SiO2 catalyst with respect to the sum of contributions from individual MoP/SiO2 and CoP/SiO2.The Agencia Estatal de Investigación (AEI) (Spain) supported this work through the project: ENE2016-74889-C4-3-R.
