| 英文摘要: |
| The oxidation stability of biodiesel is too poor to seriously restraint its development and commercial application, its usually a hot research topic about how to improve the oxidation stability of biodiesel economically and efficiently. Three methods to improve the oxidation stability of biodiesel were summarized，including adding antioxidant method, mixing method and hydrogenation method. The advantages and problems of three methods were analyzed, and a new method for improving the oxidation stability of biodiesel was explored, in order to achieve the synchronous optimization of oxidation stability and low temperature fluidity of biodiesel, and simultaneous optimization of antioxidant function and oil-soluble property of antioxidants. A new technology combining with adding new type of antioxidants and changing the biodiesel ester structures to improve the oxidation stability should be researched and developed, so that the quality of biodiesel and its application in large-scale commercial market could be promoted. It provided theoretical and technical support for the improvement of oxidation stability of biodiesel. |
