摘要
利用生命周期评价理论,建立了木薯燃料乙醇生命周期能源效率评价模型.以总体能源消耗、化石燃料消耗、石油消耗、净能源产出和能源综合利用率为评价指标,对木薯燃料乙醇进行了生命周期能源效率评价.结果表明:与汽油相比,木薯燃料乙醇生命周期整体能源消耗增加22%,化石燃料消耗降低54%,石油消耗降低96%,净能源产出偏低45%,能源综合利用率偏低8%.木薯燃料乙醇是潜力巨大的绿色燃料.
A life cycle energy assessment model of cassava-based fuel ethanol was established based on life cycle theory. The life cycle total energy, fossil fuels, and petroleum consumption, net energy yield, and overall energy utilization degree of cassava-based fuel ethanol were assessed. Compared with conventional gasoline, the life cycle total energy consumption of cassava-based fuel ethanol is higher about 22%, while the fossil fuels consumption, petroleum consumption, net energy yield, and overall energy utilization degree are lower about 54%, 96%, 45% and 8% respectively. The cassava-based fuel ethanol is a potentially significant green fuel for automobile.
