This research aims to improve biodiesel production efficiency from waste cooking oils and animal fats using hybrid nano-catalysts.
Hybrid catalyst synthesized for biodiesel production from waste feedstocks with elevated FFA content.
Performance compared to pure CaO over five reuse cycles with activity measurements.
Biodiesel quality assessed against ASTM D6751 and EN 14,214 standards.
Hybrid catalyst retains 91.4 ± 1.2% of initial activity after five cycles; pure CaO retains 87.9 ± 1.5%.
Biodiesel yield from waste cow fat reached 96.9 ± 0.7%.
All biodiesel-diesel blends meet ASTM D7467 standards, ensuring compatibility with diesel engines.
