| 生物柴油低温过滤阻塞性能差是阻碍生物柴油发展的重要原因之一。为了加强生物柴油行业规范化，促进生物柴油产业健康发展，综述了生物柴油低温过滤阻塞性能的影响因素和评价方法，并根据不同影响因素提出了建议。生物柴油中饱和脂肪酸甲酯、脂肪酸甘油酯、游离甘油、甾醇糖苷均会影响生物柴油低温过滤阻塞性能。可通过调变生物柴油分子结构，添加流动性改进剂和冷冻分离饱和脂肪酸甲酯等方法，减少饱和脂肪酸甲酯对生物柴油低温过滤阻塞性能的负面影响。ASTM D7501是评价生物柴油低温过滤阻塞性能的有效方法。在ASTM D7501基础上，制定的适用于我国生物柴油低温过滤阻塞性能评价的试验方法，对于促进我国生物柴油产品品质提升具有现实意义。 |

| Poor biodiesel low-temperature filtration blocking performance is one of the important reasons hindering the development of biodiesel. In order to strengthen the standardization of biodiesel industry and promote the healthy development of biodiesel industry, the influencing factors and evaluation methods of low-temperature filtration blocking performance of biodiesel were reviewed, and suggestions were made according to different influencing factors. Saturated fatty acid methyl esters, fatty acid glycerides, free glycerol, sterol glycosides in biodiesel can affect the low-temperature filtration blocking performance of biodiesel. The negative effect of saturated fatty acid methyl esters on the low-temperature filtration blocking performance of biodiesel can be reduced by modifying the molecular structure of biodiesel, adding flow improver and freezing separation of saturated fatty acid methyl esters. ASTM D7501 is an effective method to evaluate the low-temperature filtration blocking performance of biodiesel. The standard method of evaluating the low-temperature filtration blocking performance of biodiesel in China developed on the basis of ASTM D7501, is of practical significance to promote the quality improvement of biodiesel products in China. |
