【摘要】 提出一个新的考虑燃料可再生性的净能源成本指标,燃料指标值越低表明燃料的总体表现越好。建立了木薯-汽油混合燃料考虑可再生性的生命周期净能源成本优化模型,并对木薯乙醇-汽油混合燃料考虑可再生性的生命周期净能源成本指标进行了优化。结果表明:与考虑可再生性的净能源成本初始值比较,优化后指标值降低6.9%;通过全生命周期净能源成本优化,可以达到使其能源消耗、环境排放、生命周期成本和可再生性协调改善的目的,为木薯乙醇-汽油混合燃料的应用提供决策依据,具有重要的应用价值。更多还原

【Abstract】 A new indicator cost of net energy taking into account the renewability (CNER) of a fuel is proposed. The lower the CNER reading, the better the total performance of the fuel. An optimization model on life cycle net energy cost related to renewability of cassava-based ethanol blended gasoline fuels was given in this paper. The optimization of life cycle net energy cost related to renewability of cassava-based ethanol blended gasoline fuel was conducted. The optimized results showed that the optimization could reduce the CNER by 6.9%. Therefore, the optimization could reduce the energy consumption, environmental emissions, and life cycle productions cost and improve the renewability of fuel coordinately. The calculation could supply the important references for decision-making on implementing cassava-based ethanol blended gasoline fuels. It would have great practical value.更多还原
