The aim of the research work is to determine and analyze the factors that affect the yield ofrnbiodiesel production from algal biomass and to optimize the processing conditions. Microalgaernoil was extracted from dried and grinded consortium microalgae through soxhlet extractionrnmethod and the physicochemical properties were determined. Design Expert 7.0.0 softwarernapplication was used to statistically analyze data obtained from experimental work. The factorsrnthat affect the biodiesel yield were investigated. The density, viscosity, acid value, saponificationrnvalue and free fatty acids were recorded as 0.94g/ml, 41.85mm2/s, 4.63mgKOH/g of oil,rn201.72mg/g of oil, and 2.32% respectively.rnAlkali catalytic methanol transesterification method was employed to produce biodiesel from thernoil and to improve the physicochemical properties of the oil. Temperature is found to be thernfactor that highly affects the yield of biodiesel. An optimum yield of 89.61% (44.8ml) biodieselrnwas obtained at reaction temperature of 53.270c, 1.99% catalyst and 6.18 alchol to oil molarrnratio. The physicochemical properties of the optimum obtained biodiesl were determined and thernresults were compared with the ASTM and EN standards. The physicochemical properties werernrecorded as density (0.89g/ml), viscosity (5.5mm2/s), acid value (0.78mgKOH/g of oil), moisturerncontent (0.026%w/w), ash content (0.022%), free fatty acid (0.39%).rnThe results showed that the fuel properties are within the ASTM and EN standards and itrnsuggests the potential of algal oil as a feedstock for biodiesel industry which could be exploitedrnas an alternative source of fuel.rnKey Words: Biodiesel, Algal Biomass, Soxhlet Extraction, Transesterification &rnPhysicochemical Properties.
