Abstract
The Lipid/oil was extracted from reduced dried primary sewage sludge particle using soxhlet extraction method with Hexane and Ethyl Acetate in the ratio 2:1 as the extracting solvent. The extracted oil gave 15.03% percentage yield with density of 0.845 g/ml, pH value of 8.97, specific gravity of 0.845, viscosity of 41.20 mm2/sec, kinematic viscosity of 42.18 mm2/sec. The lipid/oil was brownish black in colour with a pungent smell. The chemical analyses revealed saponification value of 168.00 mgKOH/g, acid value of 5.60 mgKOH/g and free fatty acid value of 2.80%.
The physicochemical analyses of the biodiesel produced gave a c percentage yield of 40% biodiesel, density of 0.845 Kg/ml, pH value of 8.50, specific gravity of 0.845, kinematic viscosity of 4.80 mm2/s, acid value of 0.37 mg KOH/g, and flash point of 150°C, cloud point of 5°C and pour point of -2°C. The results of the physicochemical parameters from the research shows that the feedstock (primary sewage sludge) would be a good source for the production of biodiesel.
