    摘要:

    運用生命周期評價方法對一種以廢煎炸油為原料制取的生物柴油生命周期能耗和排放進行了分析,并將其全生命周期各項指標與傳統(tǒng)柴油路線進行了對比,,結果顯示其化石能源消耗比柴油減少了65.7%,,石油消耗較柴油全生命周期減少91.8%,常規(guī)排放也都明顯降低,,溫室氣體排放中CO2 排放下降88.1%,,總的溫室氣體排放按全球變暖潛值折算后下降86.6%。表明廢煎炸油制生物柴油是符合循環(huán)經(jīng)濟的環(huán)境友好型代用燃料,。

    Abstract:

    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.
