Abstract: A catalyst (NiW/Ti-USY) was prepared via an impregnation method. Its catalytic performance was investigated for the hydrodeoxygenation (HDO) of Jatropha oil. It was found that the support composition significantly influenced the Lewis acid site concentration, thereby affecting the deoxygenation performance. The catalyst exhibited optimal activity when the Ti loading reached 9 wt%. Furthermore, under the same support conditions, a Ni/W mass ratio of 1:9 and a total NiW loading of 30% resulted in the best catalytic performance, achieving a deoxygenation rate exceeding 90% and a minimum olefin content of 9.64%. GC-MS analysis of the product oil revealed a ratio of (C15 + C17)/(C16 + C18) greater than 10, indicating that the decarbonylation/decarboxylation (DCO/DCO₂) pathway dominated the hydrodeoxygenation process.
