摘要
运用生命周期评价方法对一种以废煎炸油为原料制取的生物柴油生命周期能耗和排放进行了分析,并将其全生命周期各项指标与传统柴油路线进行了对比,结果显示其化石能源消耗比柴油减少了65.7%,石油消耗较柴油全生命周期减少91.8%,常规排放也都明显降低,温室气体排放中CO2排放下降88.1%,总的温室气体排放按全球变暖潜值折算后下降86.6%。表明废煎炸油制生物柴油是符合循环经济的环境友好型代用燃料。
The methodology of life cycle assessment was applied to analyze the primary energy consumption and environmental emissions of biodiesel deriving from residual frying oil,compared with conventional diesel pathway.The conclusions are as follows： fossil energy consumption decreases by 65.7%,especially oil consumption decreases by 91.8%,and the criterion emissions also decreases;the total greenhouse gas emissions decreases by 86.6% with CO2 emission decreasing by 88.1%,according to conversion by means of global warming potential.It fully showed that this kind of biodiesel is an environmental friendly fuel in line with the trend of energy saving and emission reduction.
