【摘要】 木薯酒精全生命周期经济性评估是木薯酒精燃料汽车全生命周期评估和多目标优化的重要环节。通过分析木薯酒精燃料的经济性以及其影响因素 ,建立了全生命周期评估模型 ,运用全生命周期评估方法对已有数据进行分析、处理和综合 ,得到了木薯酒精全生命周期各子周期的成本构成以及经济性指标 ,得出影响木薯酒精经济性和市场竞争力的主要因素是木薯种植、副产品价格、汽油价格、零售商利润率和国家税率 ,为木薯酒精项目的实施和今后木薯酒精汽油的推广使用提供重要依据。更多还原

【Abstract】 The economic analysis of the life cycle of gasohol derived from ethanol is a very important process of the life cycle assessment and multi-objective optimization of ethanol derived from cassava.It is an important thing to first analyze the economic characteristic of ethanol derived from cassava and then the factors that affect its economic characteristic in the application of the project.By setting up the life cycle analysis model and by analyzing,processing and synthesizing the obtained data,we could obtain the cost structure of the sub-life cycle and economic index.Cassava planting cost,by-product price,gasoline price,retailers’ profit rate and national tax rate are the main factors that influence the economic characteristic and market competitive ability of gasohol derived from cassava.Finally,by comparing the gasohol derived from cassava to the traditional gasoline,the conditions that all influenced factors must satisfy are given.It is a very important thing for the future application of gasohol derived from cassava.更多还原
