Abstract

In recent years, ethanol has emerged as a popular additive for biodiesel/diesel blends, to decrease the carbon footprint left by combustion products. Nanoparticles added with biodiesel/diesel have promoted greater ignition and combustion rate, lower ignition delay, and reduced exhaust emissions. This study evaluated the filter performance of prosopis juliflora biodiesel and bioethanol mixed with diesel with selected nano particles, namely graphene(G) and graphene oxide(GO) nanoparticles. Different nano additive proportions of 50, 100, 150, 200, 250, and 300 ppm were blended in diesel blends of BED20 (10% biodiesel + 10% ethanol + 80% diesel) and the filtration characteristics of these fuel blends were evaluated to determine the best nanoparticle mixture. Tamson filter blocking tendency (TFBT) apparatus was utilized to determine filter blocking tendency (FBT). The filtration performance was measured by following the ASTM standard (D2068-14) for initial pressure, fuel temperature and fuel flow rate. Results found that the FBT tends to rise with the addition of additive proportion. It was seen that FBT values of 200 ppm of grapheme (G) nanoparticles and 250 ppm graphene oxide (GO) were found to be 1.32 and 1.4 respectively which inline the acceptable range (1.41).

纳米燃料添加剂对生物柴油-生物乙醇-柴油混合物过滤器阻塞特性的影响

摘要近年来，乙醇已成为生物柴油/柴油混合物的常用添加剂，以减少燃烧产物的碳足迹。在生物柴油/柴油中添加纳米颗粒可提高点火和燃烧速度，降低点火延迟，减少废气排放。本研究评估了桉树生物柴油和生物乙醇与柴油混合后的过滤性能，其中添加了选定的纳米颗粒，即石墨烯（G）和氧化石墨烯（GO）纳米颗粒。在 BED20（10% 生物柴油+10% 乙醇+80% 柴油）柴油混合物中混合了 50、100、150、200、250 和 300 ppm 不同比例的纳米添加剂，并对这些燃料混合物的过滤特性进行了评估，以确定最佳的纳米颗粒混合物。利用塔姆森过滤阻塞倾向（TFBT）仪器测定过滤阻塞倾向（FBT）。过滤性能是按照 ASTM 标准（D2068-14）对初始压力、燃料温度和燃料流速进行测量的。结果发现，随着添加剂比例的增加，FBT 呈上升趋势。200 ppm 的纳米石墨烯 (G) 和 250 ppm 的氧化石墨烯 (GO) 的 FBT 值分别为 1.32 和 1.4，符合可接受的范围（1.41）。

期刊介绍： The journal publishes theoretical and applied articles on the chemistry and physics of solid fuels and carbonaceous materials. It addresses the composition, structure, and properties of solid fuels. The aim of the published articles is to demonstrate how novel discoveries, developments, and theories may be used in improved analysis and design of new types of fuels, chemicals, and by-products. The journal is particularly concerned with technological aspects of various chemical conversion processes and includes papers related to geochemistry, petrology and systematization of fossil fuels, their beneficiation and preparation for processing, the processes themselves, and the ultimate recovery of the liquid or gaseous end products.
