Biodiesel from Clean Coffee Oil. All reactions were performed taking 0.5 g of clean coffee oil. 50 mg of the solid enzyme was added (enzyme load being 10%) to each set. Ethanol was added in molar ratio 4:1 (ethanol:oil). Conversion rates were measured at 24 hrs respectively through GC analysis. The experiments were done in duplicates and the error between the two sets was within 3%.
