摘　　要：为了评价当前具有开发潜能的产油小球藻生产的生物柴油品质指标是否合格,该文对三种小球藻生物柴油品质指标进行评价。该文通过含油率及FAME(脂肪酸甲酯)组成分析,利用前人已建立的FAME碳链结构与4项重要的生物柴油品质指标运动黏度、碘值、十六烷值和冷滤点间的数学模型,并参照美国、欧盟、德国和中国4个生物柴油标准,对3种小球藻F-5,F-1067,F-31油脂制取生物柴油的4项品质指标进行评价。结果表明:F-5,F-1067,F-31含油率分别为15.30%,13.13%,11.12%。F-5生物柴油运动黏度为8.3,满足美国和中国标准要求,不满足欧盟和德国标准要求,F-5生物柴油碘值、十六烷值和冷滤点分别为77,56,-3℃,均满足4个标准要求;F-1067生物柴油运动黏度和冷滤点分别为9.2和9℃,均不满足4个标准要求,F-1067生物柴油碘值和十六烷值分别为77和56,能满足各标准要求;F-31生物柴油运动黏度为11.8,不满足各标准要求,F-31生物柴油碘值和冷滤点分别为112和-9℃,能满足各国标准要求,F-31生物柴油十六烷值为47,能满足美国标准要求,但不满足其余3个标准要求。因此F-5的含油率最高,且其生物柴油在运动黏度、碘值、十六烷值和冷滤点综合表现为最佳,在3种产油小球藻中最适合生产生物柴油,为合理利用生物柴油小球藻藻种提供理论依据。In order to evaluate the quality items of microalgae biodiesel which has the potential to be exploited, this paper evaluated three kinds of Chlorella vulgaris biodiesel, providing a theoretical foundation for choosing an appropriate biodiesel Chlorella vulgaris species to produce biodiesel. Compared to petro-diesel, biodiesel has many advantages： higher biodegradability, lower sulphur content, lower carbon dioxide emission, no aromatic hydrocarbon, and lower flash point which makes the usage, transportation, management, and storage much safer. As a source of raw material for biodiesel production, oil productive Chlorella vulgaris commands high attention because of many strengths such as taking up less cultivated area, high growth rate, high oil-production efficiency, and renewability. The direct determination of biodiesel quality items is time wasting and costly, and for not yet industrialized microalgae cultivation, it is hard to acquire sufficient quantities of microalgae biodiesel. Through precursors’ mathematical model between biodiesel FAME（fatty acid methyl ester） carton chain structure and Vis（viscosity）, IV（iodine value）, CN（cetane number）, CFPP（cold filter plugging point）, compared to the biodiesel standards of America、EU、Germany and China of Vis, IV, CN, CFPP, the Chlorella vulgaris biodiesel quality items can be indirectly forecasted. This paper through analysis of the oil content and the constituting of FAME which is made from oils in three kinds of oil productive Chlorella vulgaris cells, makes use of the established mathematical model between FAME carbon chain structure and biodiesel quality items, by reference to biodiesel standards of America、EU、Germany and China, and assesses the biodiesel quality items concluding Vis, IV, CN and CFPP of Chlorella vulgaris F-5,F-1067,F-31 biodiesel. The results show that： the oil contents of Chlorella vulgaris F-5,F-1067,F-31 are 15.30%,13.13%,and 11.12%. The Vis of F-5 biodiesel is 8.3, which can meet the standards of America an
