Özet
Traditional energy sources are incompatible with contemporary environmental sustainability goals, hence renewable and eco-friendly alternatives are more popular. Due to its polyunsaturated fatty acid make up, biodiesel is prone to oxidative breakdown despite its low toxicity, biodegradability, and emissions. This reduces gasoline storage life and engine performance. Tilia platyphyllos (ıhlamur) extract, a natural phenolic, improved biodiesel-diesel (50% biodiesel + 50% diesel) blends' oxidation resistance in this research. The soxhlet extract was added to the gasoline at 3000 ppm and compared to TBHQ, a synthetic antioxidant. Thermal and chemical characterization methods FT-IR, TGA, and DSC were used to assess antioxidant activity. We tested the extract's ability to eliminate free radicals using DPPH• and ABTS•⁺ assays. The results show that Tilia platyphyllos is a powerful antioxidant that prevents biodiesel-diesel blend oxidative degradation. Biofuel technology might benefit from Tilia platyphyllos.
