Abstract
Biohythane (biohydrogen + biomethane) from lignocellulosic biomass is a win — win solution for the supply of renewable energy and valorization of organic wastes. Lignocellulosic biomass contents mainly lignin, cellulose and hemicellulose. The carbohydrate contains is approximately 70–80% (w/w) of the total biomass. These carbohydrates can be suitable raw material for dark fermentative biohydrogen production and further biomethane production. Therefore, an eco-friendly biological pretreatment was used to remove the lignin from sugarcane top. Up to 60 % w/w lignin removal was observed after 21 d at 28 oC in static condition. Confirmation of lignin removal was performed using confocal microscopy and FTIR analysis of pretreated sugarcane top. Biohydrogen production followed by biomethane production of fungal pretreated sugarcane top resulted in 77 mL hydrogen/g-VS and 158 mL methane/g-VS. This improved the overall gaseous energy recovery to 38 %.
从木质纤维素生物质中提取的生物乙烷(生物氢+生物甲烷)是可再生能源供应和有机废物增值的双赢解决方案。木质纤维素生物质主要含木质素、纤维素和半纤维素。碳水化合物约占总生物量的70-80% (w/w)。这些碳水化合物可以作为暗发酵生产生物氢和进一步生产生物甲烷的合适原料。为此，采用生态友好型生物预处理技术去除甘蔗秸秆中的木质素。在28℃的静态条件下，经过21 d，木质素的去除率高达60% w/w。利用共聚焦显微镜和FTIR分析证实了预处理甘蔗顶部木质素的去除。真菌预处理蔗顶产氢后产甲烷，氢气产量为77 mL /g-VS，甲烷产量为158 mL /g-VS。这将总气态能量回收率提高到38%。
