To enhance the efficiency of the anaerobic digestion process of lignocellulose feedstocks, there is a need for appropriate pretreatment methods. The influence of nanoparticles additive on biogas yield of new novel Xyris capensis grass as biogas feedstock was investigated. A laboratory-batch experiment was set up at mesophilic conditions (37 ± 2° C) to study the biogas production potential of Xyris capensis, and different nanoparticles were added as a means of pretreatment. 20 mg/L of Fe₃O₄, 1.4 mg/L of CuO, 10 mg/L of ZnO, and 10 mg/L of MgO were added to the anaerobic digestion process, and their influence on biogas and methane yield was compared with the untreated substrate. Biogas yield of 376.67, 156.86, 175.34, 190.00, and 290.00 mL/g VS_added was recorded for Fe₃O₄, CuO, ZnO, MgO additives, and untreated substrate, respectively, while methane yield of 282.50, 156.86, 97.66, 116.33, and 198.51 mLCH₄/g VS_added were observed, respectively. It can be observed that only 20 mg/L of Fe₃O₄ increased biogas and methane yields by 29.89 and 42.31%, respectively.

使用不同纳米颗粒添加剂提高 Xyris capensis 草的沼气产量

为了提高木质纤维素原料厌氧消化过程的效率，需要适当的预处理方法。纳米颗粒添加剂对新型沼气产量的影响山黍对草作为沼气原料进行了研究。在中温条件（37±2°C）下进行了实验室批量实验，以研究沼气生产潜力山黍，并添加不同的纳米颗粒作为预处理手段。厌氧消化过程中添加20 mg/L Fe ₃ O ₄、1.4 mg/L CuO、10 mg/L ZnO、10 mg/L MgO，比较其对沼气和甲烷产率的影响。未经处理的基材。Fe ₃ O ₄ 、CuO、ZnO、MgO 添加剂和未处理基质的沼气产量分别为 376.67、156.86、175.34、190.00 和 290.00 mL/g VS_添加，而甲烷产量分别为 282.50、156.86、97.66、116.33 ，和198.51 mLCH ₄ /g VS_添加，分别观察到。可以看出，仅20mg/L的Fe ₃ O ₄就使沼气和甲烷产量分别增加了29.89%和42.31%。
