Abstract

In the aviation sector, the use of biofuels has increased worldwide, therefore, this study assesses the environmental impact of these mass-based blends, named BK0, BK10, BK20 and BK30, according to their composition (Biodiesel + Kerosene) and the percentage of mass fraction. The study uses life cycle analysis with the SimaPro software and the Ecoinvent database for Colombia. The stages of cultivation, oil extraction and refining were established for biodiesel, while for the kerosene the stages defined were crude oil extraction and its refining. Results show that the stage with the greatest impact is the cultivation and extraction for both the category of freshwater ecotoxicity, acidification and terrestrial eutrophication

航空用生物柴油混合物的生命周期分析

在航空领域，生物燃料的使用在全球范围内有所增加，因此，本研究根据其成分(生物柴油+煤油)和质量分数的百分比，评估了这些以质量为基础的混合物的环境影响，命名为BK0, BK10, BK20和BK30。该研究使用了哥伦比亚的SimaPro软件和Ecoinvent数据库的生命周期分析。确定了生物柴油的种植、提取和精炼阶段，煤油的阶段确定为原油提取和精炼阶段。结果表明，对淡水生态毒性、酸化和陆地富营养化影响最大的阶段是养殖和采掘阶段
