The effects of pre-treatment methods on saccharification and hydrogen fermentation of Chlorella pyrenoidosa biomass were investigated. When raw biomass and biomass pre-treated by steam heating, by microwave heating, and by ultrasonication were used as feedstock, the hydrogen yields were only 8.8-12.7 ml/g total volatile solids (TVS) during dark fermentation. When biomass was pre-treated by steam heating with diluted acid and by microwave heating with diluted acid, the dark hydrogen yields significantly increased to 75.6 ml/g TVS and 83.3 ml/g TVS, respectively. Steam heating with diluted acid is the preferred pre-treatment method of C. pyrenoidosa biomass to improve hydrogen yield during dark fermentation and photofermentation, which is followed by methanogenesis to increase energy conversion efficiency (ECE). A total hydrogen yield of 198.3 ml/g TVS and a methane yield of 186.2 ml/g TVS corresponding to an overall ECE of 34.0% were obtained through the three-stage process (dark fermentation, photofermentation, and methanogenesis).

研究了预处理方法对小球藻生物质糖化和氢发酵的影响。当使用通过蒸汽加热,通过微波加热和通过超声处理的原始生物质和生物质作为原料时,在黑暗发酵期间,氢产率仅为8.8-12.7毫升/g总挥发性固体 (TVS)。当通过用稀酸进行蒸汽加热和用稀酸进行微波加热对生物质进行预处理时,暗氢产量分别显著增加至75.6毫升/g TVS和83.3毫升/g TVS。用稀酸蒸汽加热是C. pyrenoidosa生物质的首选预处理方法,以提高黑暗发酵和光发酵过程中的氢产量,随后是甲烷生成以提高能量转化效率 (ECE)。通过三阶段过程 (暗发酵、光发酵和产甲烷) 获得了198.3毫升/g TVS的总氢产率和186.2毫升/g TVS的甲烷产率,对应于34.0% 的总ECE。
