【摘要】 建立了基于生命周期影响评价的车用替代燃料多目标优化模型,以车用替代燃料生命周期影响总水平值为优化目标,并以木薯乙醇为例,对车用替代燃料进行了多目标优化。结果表明,多目标优化后木薯乙醇生命周期影响总水平值降低44.7%,建议木薯乙醇在汽油中的混合比例为95%,在乙醇生产过程中使用天然气燃料。更多还原

【Abstract】 A multi-objective optimization model of automotive alternative fuels based on its life cycle impact assessment was established in this paper,using the overall environment impact value(OEIV) as the optimization objective.And,multi-objective optimization of cassava-based ethanol was done as a case study.The multi-objective optimization results shown that OEIV could be reduced about 44.7%,the blend ratio of cassava-based ethanol into gasoline should be 95%,and the processing fuel during ethanol conversion stage should be natural gas.更多还原
