AbstractThis study focuses on a wide range of socio-political factors that contribute to the production and utilization of biogas in Mokambo, a peri-urban area of Mufulira in Zambia. The study employed a variety of qualitative techniques which includes in-depth interviews, focus group discussions (FGDs), and case study to answer the research questions. Revealed here is that there are essentially five issues driving biogas production: environmental protection and climate change; economic view and sustainable development; poverty reduction and international aid; and agricultural production. The research identifies four types of problems: institutional, situational, infrastructure and technical, and dispositional. The study emphasizes the local government’s effort to improve its strategies in relation to community awareness for the production and adoption of biogas in Zambia. This is combined with ongoing dialogue among stakeholders with a holistic approach towards a smooth and steady renewable energy transition.Keywords: Drivers of biogasrenewable energyenergy transitionperi-urbanlocal governmentZambia Disclosure statementNo potential conflict of interest was reported by the authors.
摘要本研究聚焦于影响赞比亚穆富里拉近郊地区Mokambo沼气生产和利用的一系列社会政治因素。该研究采用了多种定性技术,包括深度访谈、焦点小组讨论(fgd)和案例研究来回答研究问题。这里揭示的是,推动沼气生产的主要有五个问题:环境保护和气候变化;经济观与可持续发展;减少贫困和国际援助;还有农业生产。该研究确定了四种类型的问题:制度、情境、基础设施和技术以及配置。该研究强调了当地政府努力改善其战略,以提高社区对赞比亚生产和采用沼气的认识。这与利益相关者之间的持续对话相结合,以整体方法实现平稳稳定的可再生能源转型。关键词:沼气驱动因素可再生能源能源转型近郊地方政府赞比亚披露声明作者未报告潜在利益冲突。

Abstract . Biofuels, which are widely used as alternative fuels to reduce fossil fuel consumption and replace them with fossil fuel-like energy sources, are increasingly being supplemented with nanoparticles (NP) to overcome their limitations, including lower energy content and higher emissions. The study aimed to examine the impact of Fe-Ni-TiO2/activated carbon (AC) nanoparticles, produced by the authors, on engine performance and emissions when added to diesel/biodiesel fuel blends. The produced Fe-Ni-TiO2/AC NP was employed as an additive in palm oil (PO)/diesel fuel blends at 50 and 100 ppm concentrations. The results revealed that compared to standard diesel, employing Fe-Ni-TiO2/AC NPs lowered emissions including smoke, carbon monoxide (CO), and hydrocarbon (HC) in all fuel blends while increasing nitrogen oxide (NOx). In the DNP30-100 fuel blend at 2500 W engine load, there was an increase in NOx by 8% and a decrease in CO, HC, and smoke emissions by 70.3%, 86.3%, and 57.5%, respectively, compared to standard diesel. Furthermore, a decrease of 11.38% was observed in brake-specific fuel consumption, while brake thermal efficiency increased by 16.59% compared to diesel. The overall results suggest that using Fe-Ni-TiO2/AC as an additive in a diesel–biodiesel fuel blend can improve engine performance and decrease emissions.
摘要生物燃料被广泛用作替代燃料,以减少化石燃料的消耗,并以类似化石燃料的能源替代化石燃料。目前,生物燃料越来越多地被纳米颗粒(NP)补充,以克服其局限性,包括较低的能量含量和较高的排放。该研究的目的是检测作者生产的Fe-Ni-TiO2/活性炭纳米颗粒添加到柴油/生物柴油燃料混合物中对发动机性能和排放的影响。制备的Fe-Ni-TiO2/AC NP作为棕榈油(PO)/柴油混合物的添加剂,浓度分别为50和100 ppm。结果显示,与标准柴油相比,使用Fe-Ni-TiO2/AC NPs降低了所有燃料混合物中的烟雾、一氧化碳(CO)和碳氢化合物(HC)排放,同时增加了氮氧化物(NOx)。在2500 W发动机负荷下,DNP30-100混合燃料与标准柴油相比,NOx排放量增加了8%,CO、HC和烟雾排放量分别减少了70.3%、86.3%和57.5%。此外,与柴油相比,制动比油耗降低11.38%,而制动热效率提高16.59%。总体结果表明,在柴油-生物柴油混合燃料中使用Fe-Ni-TiO2/AC添加剂可以提高发动机性能并减少排放。
