Abstract

Abstract The main objective of this study is to investigate some important fuel properties of expanded polystyrene (EPS)-infused biodiesel blends without and with the addition of a certain percentage of diethyl ether (DEE), a cetane number (CN) enhancer. The originality of this study is the use of high-CN DEE as an additive for EPS-infused canola biodiesel to investigate a diesel engine’s performance and emissions. Furthermore, we performed a microscopic study (of structure and particle size distribution) of EPS-infused canola biodiesel blends without and with DEE as an additive. Biodiesel is an effective solvent for EPS. EPS-infused biodiesel can be used in diesel engines for power production, and it can be a supplementary energy source for IC engines. This study investigates the EPS-infused biodiesel blend performance and emission in a direct injection (DI) diesel engine at low, medium, and high loads, each at 1000, 2100, and 3000 rpm. The EPS was dissolved in biodiesel at varying concentrations (2, 6, and 10 g/L) at room temperature (25 °C). The results for different EPS-infused biodiesel blends are compared with those of pure diesel and biodiesel, and EPS dissolution and performance improvements with DEE were achieved.

添加DEE的EPS生物柴油及其在柴油机中的性能和排放的微观研究

摘要:本研究的主要目的是研究膨胀聚苯乙烯(EPS)注入生物柴油共混物在不添加和添加一定比例的十六烷数增强剂乙醚(DEE)的情况下的一些重要燃料性能。本研究的独创性是使用高cn DEE作为eps注入的油菜籽生物柴油的添加剂，以研究柴油发动机的性能和排放。此外，我们进行了一个微观研究(结构和粒度分布)的eps注入的油菜籽生物柴油混合物，不添加和添加DEE。生物柴油是EPS的有效溶剂。注入eps的生物柴油可用于柴油机发电，也可作为内燃机的补充能源。本研究考察了直接喷射(DI)柴油发动机在低、中、高负荷(分别为1000、2100和3000转/分)下注入eps的生物柴油混合物的性能和排放。EPS在室温(25°C)下以不同浓度(2、6和10 g/L)溶解在生物柴油中。通过与纯柴油和生物柴油进行比较，发现DEE对EPS的溶解作用和性能的改善。

期刊介绍： Current energy systems need a vast transformation to meet the key demands of the 21st century: reduced environmental impact, economic viability and efficiency. An essential part of this energy revolution is bioenergy. The movement towards widespread implementation of first generation biofuels is still in its infancy, requiring continued evaluation and improvement to be fully realised. Problems with current bioenergy strategies, for example competition over land use for food crops, do not yet have satisfactory solutions. The second generation of biofuels, based around cellulosic ethanol, are now in development and are opening up new possibilities for future energy generation. Recent advances in genetics have pioneered research into designer fuels and sources such as algae have been revealed as untapped bioenergy resources. As global energy requirements change and grow, it is crucial that all aspects of the bioenergy production process are streamlined and improved, from the design of more efficient biorefineries to research into biohydrogen as an energy carrier. Current energy infrastructures need to be adapted and changed to fulfil the promises of biomass for power generation. Biofuels provides a forum for all stakeholders in the bioenergy sector, featuring review articles, original research, commentaries, news, research and development spotlights, interviews with key opinion leaders and much more, with a view to establishing an international community of bioenergy communication. As biofuel research continues at an unprecedented rate, the development of new feedstocks and improvements in bioenergy production processes provide the key to the transformation of biomass into a global energy resource. With the twin threats of climate change and depleted fossil fuel reserves looming, it is vitally important that research communities are mobilized to fully realize the potential of bioenergy.
