| Abstract: |
| As important alternative fuel of petrochemical diesel, the second generation biodiesel has a good application prospect, and the catalyst is an important factor restricting its development. The new research progress on catalysts for oil hydrodeoxygenation was reviewed, including the mechanism of hydrodeoxygenation reaction, the active components, promoters and supporters of the catalyst. The reason of catalyst deactivation was analyzed. Further,the development direction in the future was pointed out. The expensive price of precious metal catalysts leads to high costs in the production process of biodiesel, which limits its large-scale industrial production and technological development. Transition metal catalysts are cheap, but they have issues such as poor catalytic performance and easy deactivation. Promoters and supporters also greatly affect the activity, selectivity, and stability of catalysts. In summary, developing new, efficient, and stable oil hydrodeoxygenation catalysts by modifying non precious metal catalysts, adding promoters, or using modified composite supporters, is the future development direction. |
