Résumé

Energy plays a crucial role in the development of modern society. However, fossil fuels, which remain the world’s primary energy source, are limited and their use significantly contributes to climate change. In this context, renewable energies, which are sustainable and environmentally friendly, have attracted growing attention. Biodiesel, produced from vegetable oils or animal fats, represents a promising alternative to fossil diesel due to its similar physicochemical properties, allowing its use in existing engines without modification. In this study, two types of biodiesel were synthesized from different vegetable oils: new sunflower oil and waste cooking oil. The produced biodiesels were characterized by determining key physicochemical properties, including viscosity, acidity, and cetane index. In addition, FT-IR and FT-Raman spectroscopic analyses were performed to identify the characteristic functional groups and confirm the conversion of triglycerides into fatty acid esters. The experimental results were compared with European and American biodiesel standards in order to evaluate their conformity and potential as substitutes for petroleum diesel.
