摘要
运用生命周期评价方法对菜籽油生物柴油的能源效率及环境效益进行了系统评价。研究结果表明,生物柴油比石化柴油具有更高的能量净值,能量输出远大于能量输入;使用生物柴油降低了温室气体和CO、HC、NOx等空气污染物的排放,并减少了对水体和土壤的污染,这说明生物柴油的可再生性及环保性具有良好的生态效益。
On the base of the theory of the industrial ecology,the life cycle assessment of rapeseed biodiesel is performed for its energetic effieney and environmental benefit. The results indicate that eompard to diesel fuel, energy aceummulated in biodiesel fuel life cycle is much bigger than the energy consumption. The assessment of life cycle emission indicates using biodiesel help reduce the emissions of CO2 and such air pollution as CO, HC, and NOx. Furthermore, it makes less polutting to the water and soil. So the biodiesel show good renewability and ecological benefit.
