Abstract: Recent advances in catalysts for the hydrodeoxygenation of vegetable oil were reviewed in this paper，including the hydrodeoxygenation mechanism of vegetable oil，the selection of active components，the selection and modification of the support for the supported catalysts，the preparation of unsupported catalysts and the stability of hydrodeoxygenation catalysts. It is pointed out that the main problems at present are the low catalytic activity and poor vaporous-thermal stability，so the study on novel hydrodeoxygenation catalysts with suitable acidity and pore structure，high activity，good vaporous-thermal stability becomes important in future.
