摘  要:
利用生命周期评价(LCA)理论,对秸秆制备燃料二甲醚(DME)、柴油和汽油进行了生命周期能源、环境评价,并进行了综合指标比较。结果表明,二甲醚的生命周期能源消耗增加,石油消耗降低;生命周期全球变暖潜力(GWP)、光化学烟雾潜力(POCP)和气溶胶潜力(AQP)降低,酸化潜力(AP)增高。从平衡能源、环境影响方面考虑,生物质基二甲醚作为燃料推广是可行的。

摘  要:
Life cycle energy and environment assessment were carried out for comparing the energy consumption,environmental impacts,and integration assessment results of biofuel DME,diesel and gasoline.Compared with diesel and gasoline,the total energy consumption for the life cycle of bio-DME is larger,but the petroleum consumption decreases;In life cycle bio-DME has lower GWP,POCP and AQP,which is more beneficial to the environment than gasoline and diesel,only the AP is higher.The integrated index of LCA indicates the feasibility of bio-DME as a substitute fuel.
