This study examines how a calcium oxide catalyst supported on alumina improves biodiesel yield from waste peanut oil, indicating potential for sustainable energy solutions.
Key Points
The study achieved a biodiesel yield of 97% using biogenic calcium oxide catalysts derived from animal bones.
Key fatty acid methyl esters identified included methyl oleate, methyl stearate, and methyl linoleate, with over 96% purity.
Statistical modeling confirmed that reaction temperature and time significantly influence biodiesel yield with a good fit (R2 > 0.9311).
Optimizing catalytic processes indicates the potential of waste valorization to increase sustainable biodiesel production.
