煤基甲醇生命周期温室气体排放评价 -

将Input-Output分析方法引入LCA评价中,建立了Hybrid LCA评价方法。利用该方法对煤基M100(100%甲醇)车用替代燃料生命周期温室气体排放进行评价。结果表明:相同热值煤基M100燃料温室气体排放比传统汽油高许多,因此建议在生产阶段采用CO2捕集和储存技术和重点提高煤炭燃烧利用效率。 Applying the input-output method to LCA,the input-output hybrid LCA assessment is established.With this method,life cycle greenhouse gases emission of coal-based Methanol 100 as an alternative vehicle fuel are analyzed.Compared with traditional gasoline with same heat value,coal-based M100 will result heavier greenhouse effect.So application of carbon captured and storage equipments is suggested in the production stage and the combustion efficiency of coal should be improved greatly
