| 摘 要： | 能源利用技术的能源转换效率是其技术评价的重要基础。秸秆沼气发酵技术一方面受到高度关注与国家政策支持,另一方面其能源转换效率研究却几乎为零。文章提出一种体现厌氧生化过程细菌能量学成果的能效分析方法,对秸秆沼气发酵进行了能效分析。通过典型秸秆主要组分厌氧降解率和厌氧过程细菌能量学分析,得出现有秸秆沼气发酵技术的最大能源转换效率低于25%的结论。

| Abstract: | The energy conversion efficiency is a principal reference for the technical assessment and application strategy of one energy technology.The technology of straw-to-biogas has get great attention and the government support;On the other hand,there is few studies on its energy conver-sion efficiency.Based on the bacteria-level energetic flux analyses in the anaerobic process,a new energy conversion efficiency method has been proposed in this pater.The straw-to-biogas energy efficiency is analyzed.According to ... |
