Effect of diesel-biodiesel and diesel-biodiesel-ethanol blends on physicochemical properties and gases emission of Baobab biodiesel


Hiam M Mohammed, Elfatih A Hassan, Mohammed E Osamn

Biodiesel from Baobab seed oil was produce using transesterification reaction. The blends ratios were as follow; B20 (20% biodiesel, 80% diesel) B20E20 (20%biodiesel, 20%Ethanol, 60%diesel) and B20E30 (20%biodiesel, 30%Ethanol, 50%diesel). Biodiesel, B20, B20E20, and B20E30 had the following physicochemical properties: Density at 15°C g/cm3 (0.8866, 0.8519, 0.8403, and 0.8864 g/cm3 respectively), Kinematic viscosity in 40°C (5.8, 3.6, 3.4, and 2.7 cSt respectively), total Acid Number mgKOH/g (0.20, 0.16, 0.14, and 0.13), Calorific value (44.051, 44.354, 44.456, and 44.5 MJ kg -1 respectively), Cloud point (+7, +12, +8, and +8 °C), Pour point (+6, -6, -8,and-12°C), flash point was 80 for biodiesel and 67 for B20 Water Content wt% (0.1, 0.05, 0.056, and 0.048) Copper Strip Corrosion 3 Hours at 100oC ( 1b, 1a, 1a, and1a). The experimental results of emissions in diesel engine at different speeds for standard diesel and blends showed that the carbon dioxide and NOX emissions decrease when blends used over diesel. B20 (20% biodiesel and 80% diesel) showed lowest emissions levels.
