| 摘 要： | 以传统柴油为比较基准,采用生命周期评价的方法分析了微藻生物柴油的生命周期化石能耗、石油能耗和温室气体(Greenhouse Gas Emissions,GHG)排放.结果表明:微藻生物柴油生命周期上游阶段的化石能耗比传统柴油的高,石油能耗和温室气体排放较低;微藻生长阶段是化石能耗强度最集中的过程(如大量肥料的使用和电力等过程燃料的投入),其次为油脂提取阶段;使用微藻生物柴油(M-BD100)可减少石油资源消耗和降低温室气体排放;在现有条件下,微藻生物柴油掺混20%(体积比)的传统柴油可降低生命周期化石能耗和温室气体排放.

| Abstract: | This paper presents the impact of energy consumption and greenhouse gas (GHG) emissions of microalgal biodiesel compared with the conventional petroleum based diesel via life cycle assessment (LCA). The results indicated that the fossil energy consumption of upstream stage for microalgal biodiesel was higher than that of petroleum based diesel, except for petroleum consumption and GHG emissions. The growth of microalgae was the most energy intensive stage during its life cycle, followed by oil extraction stage. From the perspective of the full life cycle, microalgal biodiesel (BD100) can reduce the life cycle petroleum consumption and GHG emissions. At present, the use of BD20 can decrease the life cycle fossil energy consumption and GHG emissions. |
