摘要
建立了木薯乙醇汽油生命周期能源、环境和经济性评价模型,并对木薯乙醇汽油进行了生命周期能源、环境及经济性评价。结果表明:与普通汽油比较,木薯乙醇汽油生命周期整体能源消耗升高,石油消耗降低;生命周期温室气体、VOC和CO等污染物排放降低;销售价格升高并需要政府补贴。从平衡生命周期能源消耗、环境排放和经济性角度出发,木薯乙醇汽油可以在广西推广使用。
A life-cycle energy, environment, and economic assessment model of cassava-based ethanol gasoline had been carried out in this paper. Then, the life-cycle energy, environment, and economy of cassava-based ethanol gasoline used as automotive fuel were assessed. Comparing with conventional gasoline, cassava-based ethanol gasoline has higher life-cycle total energy consumption, lower petroleum consumption, lower greenhouse effect,VOC, and CO pollutants, higher price, and needs subsidy. Form the viewpoint of balancing energy, environment, and economic, it could be implemented in Guangxi province of China.
