A novel electrohydrolysis pretreatment enhances methane production from lignocellulose material during anaerobic digestion. A biochemical methane potential assay was carried out to determine the effect of direct current and the efficacy of electrohydrolysis pretreatment on biogas production. Methane yield was increased by 13.8%, to 301 ± 3 mL CH/g VS, when lignocellulosic waste was pretreated with electrohydrolysis. A net energy gain of 13,224 kJ was realized after electrohydrolysis pretreatment, which was 1.51 times higher than reported for thermal pretreatment. In addition, two kinetic models were used, including the modified Gompertz model to reproduce the experimental data. These finding support the potential for increased methane recovery from lignocellulosic waste using electrohydrolysis as a pretreatment.
一种新型电水解预处理方法可提高木质纤维素材料在厌氧消化过程中的甲烷产量。采用生物化学甲烷潜力测定法来确定直流电的影响和电水解预处理对沼气生产的效果。当木质纤维素废物进行电水解预处理时，甲烷产量增加了 13.8%，达到 301±3mLCH/gVS。电水解预处理后可实现净能量增益 13224kJ，是热预处理的 1.51 倍。此外，还使用了两种动力学模型，包括修正的 Gompertz 模型来再现实验数据。这些发现支持了使用电水解作为预处理方法从木质纤维素废物中提高甲烷回收的潜力。
