Abstract: Fatty acid based feedstocks such as vegetable oil, tall oil and animal fat attract much attention as renewable sources for fuel production. Hydrodeoxygenation (HDO) of these crudes leads to the mixture of hydrocarbons (“green” or “renewable” diesel). Transition metal phosphides are considered as promising catalysts for HDO processes. The aims of the present work are the study of the Ni2P/SiO2 catalysts in HDO of model compounds – aliphatic methyl esters Cn-1H2n-1COOCH3 (n = 7, 12 and 16), investigation of reaction conditions and carbon chain length influence on catalytic properties. Ni2P/SiO2 catalysts were synthesized by incipient wetness impregnation of SiO2 followed by reduction in situ in reactor. Two parallel reaction pathways occur on the catalysts surface during HDO: decarboxylation/decarbonylation through CO2, СО and Сn-1H2n hydrocarbons formation and direct hydrodeoxygenation through H2O and СnH2n+2 hydrocarbons formation. Hydrocarbon chain length influence on activity but almost does not effect on selectivity
