A three-stage anaerobic fermentation process including H(2) fermentation I, H(2) fermentation II, methane fermentation was developed for the coproduction of hydrogen and methane from cornstalks. Hydrogen production from cornstalks using direct microbial conversion by Clostridium thermocellum 7072 was markedly enhanced in the two-stage thermophilic hydrogen fermentation process integrated with alkaline treatment. The highest total hydrogen yield from cornstalks in the two-stage fermentation process reached 74.4 mL/g-cornstalk. The hydrogen fermentation effluents and alkaline hydrolyzate were further used for methane fermentation by anaerobic granular sludge, and the total methane yield reached 205.8 mL/g-cornstalk. The total energy recovery in the three-stage anaerobic fermentation process integrated with alkaline hydrolysis reached 70.0%.
针对玉米秸秆的生物制氢和生物制甲烷，本研究开发了包括 H2 发酵 I、H2 发酵 II 和甲烷发酵的三阶段厌氧发酵工艺。通过热嗜纤维梭菌 Clostridium thermocellum 7072 的直接微生物转化，在与碱性处理集成的两段式高温产氢发酵工艺中，玉米秸秆的产氢效率显著提高。两段式发酵工艺中，玉米秸秆的总氢气产量最高可达 74.4 毫升/克-秸秆。氢气发酵废水和碱性水解物进一步通过厌氧颗粒污泥进行甲烷发酵，总甲烷产量达到 205.8 毫升/克-秸秆。集成碱性水解的三阶段厌氧发酵工艺的总能量回收率达到 70.0%。
