摘要

本研究探讨了生物柴油作为替代燃料的重要性,它可以减少柴油发动机的污染物排放,减轻化石燃料对生态环境的影响。生物柴油提取自可再生资源,通过酯交换反应生产,具有显著的环境效益。本研究旨在提供使用葡萄籽、玉米和亚麻籽生物柴油的生物柴油-柴油混合物的蒸馏数据;分析的体积成分为柴油中生物柴油的 20%、40%、60% 和 80%。这些数据是使用安东帕 Diana 700 自动蒸馏器获得的。此外,密度、粘度、折射率、十六烷值和闪点等特性也根据美国材料与试验协会 - ASTM D975(柴油)和 ASTM D6751(生物柴油)标准进行了评估。根据 Riazi 和 Daubert 建立了两个相关模型,用于计算柴油和生物柴油混合物的馏程温度和馏程曲线。共确定了 207 个实验馏分点。结果表明,生物柴油的加入会使馏分曲线向更高温度移动,从而影响挥发性和燃烧。由于化合物之间的化学性质不同,生物柴油的假纯曲线与柴油的假纯曲线差别很大。生物柴油和柴油 + 生物柴油混合物的拟议相关性表明,生物柴油在 10%、50% 和 90%蒸馏体积下的蒸馏温度的平均绝对百分比偏差(MAPD)分别为 3.61%、1.59% 和 1.61%。混合物中生物柴油的体积比例分别为 20%、40%、60% 和 80%时,生物柴油含量的偏差分别为 1.46%、1.25%、1.06% 和 0.83%,并没有随着生物柴油含量的增加而出现系统性偏差。针对生物柴油和柴油 + 生物柴油混合物提出的相关性显示出了可接受的偏差,极大地促进了对生物燃料的理解和发展。将混合物的物理性质与 ASTM D975 标准进行比较,结果表明,在生物柴油占体积的 67-76% 和密度占体积的 37% 的范围内,混合物的物理性质均符合标准。

Distillation analysis of diesel-biodiesel mixtures: A comparative study with ASTM norms, experimental data, and novel correlations
This study investigates the importance of biodiesel as an alternative fuel to reduce pollutant emissions from diesel engines and mitigate the ecological impacts of fossil fuels. Biodiesel, derived from renewable sources, is notable for its environmental benefits and is produced through a transesterification reaction. This study aims to provide distillation data for biodiesel-diesel blends using grape seed, corn, and linseed biodiesel; the volumetric compositions analyzed are 20 %, 40 %, 60 %, and 80 % biodiesel in diesel. These data were obtained with an Anton Paar Diana 700 automatic distiller. Additionally, properties such as density, viscosity, refractive index, cetane index, and flashpoint were evaluated by the American Society for Testing and Materials − ASTM D975 (diesel) and ASTM D6751 (biodiesel) standards. Two correlative models based on the Riazi and Daubert were developed to calculate distillation temperatures and the distillation curves of diesel and biodiesel mixtures. A total of 207 experimental distillation points were determined. The results indicated that biodiesel addition shifts the distillation curves to higher temperatures, affecting both volatility and combustion. The pseudopure curves of biodiesels differed significantly from those of diesel because of the chemical differences between the compounds. The proposed correlations for biodiesel and diesel + biodiesel mixtures exhibited mean absolute percentage deviation (MAPD) of 3.61 %, 1.59 %, and 1.61 % for distillation temperatures at 10 %, 50 %, and 90 % of the distilled volume, respectively, for biodiesel. For the volumetric proportions of 20 %, 40 %, 60 %, and 80 % of biodiesel in the mixture, deviations of 1.46 %, 1.25 %, 1.06 %, and 0.83 % were observed without systematic deviations with increased biodiesel content. The correlations proposed for biodiesel and diesel + biodiesel mixtures demonstrated acceptable deviations, significantly contributing to the understanding and advancement of biofuels. Comparisons of the physical properties of the blends with the ASTM D975 standard confirmed compliance up to a proportion in the range of 67–76 % biodiesel by volume for viscosity and 37 % for density.
