| 摘要: | 本文以1hm2土地种植生产的玉米秸秆为基准, 研究了生物质转化为生物质汽油过程中的能源效率和污染物排放. 综合分析了玉米农作物在种植生长、收储运和转化阶段的能量投入和环境贡献值, 比较了直接法和间接法制生物质汽油这两种技术的能源与环境效益. 结果表明直接法制汽油技术的能量投入低, 间接法单位排污量相对少但能量投入高. 相比直接法, 间接法制汽油所投入的能量多22.45%, 单位能量产生的全球变暖潜值和酸化效应分别减少23.24%和5.92%. |
| Abstract: | In this paper, the total cornstalk yield of one hectare is used as the baseline of comparison, and analysis of energy efficiency and total pollutant emissions during gasoline synthesis from biomass is performed. The energy consumption and environmental impact during corn growth, cornstalk harvest, transportation and conversion to gasoline is analyzed. The energy consumption and environmental benefits of direct and indirect conversion process of biomass is compared. The results show that direct conversion process consumes less energy, while indirect conversion process has less environmental impact but higher energy consumption. Indirect conversion of cornstalk consumes 22.45% more energy but has 23.24% less global warming potential (GWP) and 5.92% less acidification potential (AP) than those of direct method. |
