中文摘要：

过度使用化石燃料所造成的能源短缺和环境污染已对全球经济的可持续发展带来严重挑战。人们尝试以粮食为原料生产生物乙醇燃料以缓解对化石燃料的依赖，已导致国际市场粮食价格的大幅度上涨和全球性粮食恐慌。因此，研究开发新的清洁替代能源已成为一项十分紧迫的任务。由于氢能具有清洁、高效和可再生的特点而备受关注。在诸多的制氢方法中，发酵法生物制氢具有反应条件温和、

英文摘要：

The effects of acid hydrolysis pretreatment of corn cob on saccharification efficiency and fermentation bio-hydrogen production were investigated by orthogonal test design. The hydrolysis pretreatment of corn cob with dilute sulfuric acid was essential for adequately converting substrate into soluble saccharides and bio-hydrogen. The experimental results showed that acid hydrolysis pretreatment of corn cob was found most effective at hydrolysis temperature of 115℃, sulfuric acid concentration of 1.0%, hydrolysis time of 1.5 h and solid-liquid mass ratio 1 ： 10, in which both maximum saccharification efficiency of 0. 5433 g· （g TVS）^-1 and bio-hydrogen yield of 85.8 ml H2 · （g TVS）^-1 were observed. In addition, the mechanisms of degrading corn cob by acid hydrolysis and hydrogen fermentation were also discussed by means of X-ray diffraction （XRD） analysis and crystallinity calculation.
