Abstract

 Abstract — Different methods and processes of optimizing the yield of biogas are currently being explored globally. In this study, the use of Iron oxide nanoparticles as an additive to improve the biogas production was carried out. Iron oxide nanoparticles (ION) were synthesized by hydrothermal method. And subsequently, the biomethane potential test was conducted in a 500 mL batch reactor set at mesophilic conditions for a retention time of 15 days. A combination ratio of 100ppm ION to 1.6 g/VS winery solid waste (WSW) was used to run duplicate experiments. Results showed a cumulative biogas yield of 17,17mL /g.VS added for WSW alone (W1) compared to 56,93mL/g.VS added for the combination of WSW and ION (W2) which represents a biogas increase of 232%. In conclusion, ION has chemical properties that boost biogas production irrespective of the type of substrate used. The finding is of interest to the biogas industry along with waste management practitioners. studies made on nanomaterials revealed either negative or positive results with some very low biogas yields in some cases.

氧化铁纳米颗粒应用于酒庄固体废弃物中提高沼气产量

摘要-目前全球正在探索优化沼气产量的不同方法和过程。在本研究中，使用氧化铁纳米颗粒作为添加剂来提高沼气产量。采用水热法制备了氧化铁纳米颗粒。随后，在500 mL间歇式反应器中进行生物甲烷电位测试，设置中温条件，保留时间为15天。采用100ppm离子与1.6 g/VS酒庄固体废物(WSW)的组合比例进行重复实验。结果表明，累计产气量为17.17 ml /g。单独添加WSW (W1) VS为56,93ml /g。WSW和ION (W2)的组合增加了VS，这代表沼气增加了232%。总之，无论使用何种基质，离子都具有促进沼气生产的化学特性。这一发现引起了沼气行业和废物管理从业者的兴趣。对纳米材料的研究表明，在某些情况下，沼气产量非常低，结果要么是消极的，要么是积极的。Otero-Gonzales等[9]在2014年长期研究了氧化铜纳米颗粒(CuO)的作用，证明了其抑制作用

期刊介绍： Střed | Centre is a peer-reviewed journal focused on studies of the society, culture and politics in Central Europe of the 19th and 20th centuries. The journal is ecumenical in its selected methodological and disciplinary approaches and strives to give space to scholars working on the broad field of social sciences and humanities, who are involved in studies of the given period and geographical area. Střed /Centre aims at interconnecting the extensive and simultaneously rather fragmented field of research dedicated to Central Europe from the viewpoint of various disciplines. Therefore it publishes original studies from individual fields, particularly studies with the ambition to step over the border defined by disciplinary divisions and to connect more disciplines in a productive dialogue. As a peer-rewieved journal Střed | Centre was founded on January 1, 2009 and is issued twice a year. It is oriented on monothematic issues presenting inter-related scientific essays. Topics of individual issues are published on the journal web page well in advance. Střed | Centre comes out twice a year, in April and October, and is included in the list of peer-reviewed non-impact periodicals issued in the Czech Republic.
