中文摘要：

对木质纤维素生物制氢的三种预处理方法进行了能值分析与比较.结果表明,氨纤维爆破法能值置换比最低,能值产出率最高,但现阶段设备成本比较高,稀酸由于价格低廉,应用范围广,环境承载力比较高.

英文摘要：

On the basis of lignocellulose as substrate,biohydrogen production process has three kinds of pretreatment methods.Emergy analysis is applied to evaluate three typical ones from those methods.The result shows that ammonia fiber blasting has the lowest Tr and highest EYR among three methods,but its equipment cost is high.
