Abstract
AbstractReserves of fossil fuels are depleting gradually and non-renewable in nature. This influences the researchers to identify new renewable and greener alternative fuel for IC engine. Current paper is focussed on microalgae cultivation, oil extraction and its blends with fossil diesel for diesel engines performance analysis. Extraction of oil from microalgae biomass is done by Soxhlet apparatus and then converted into biodiesel by transesterification. Prepared blends are named as MBD10 (diesel 90%, microalgae biodiesel 10%), MBD15 (diesel 85%, microalgae biodiesel 15%), MBD20 (diesel 80%, microalgae biodiesel 20%), MBD25 (diesel 75%, microalgae biodiesel 25%), MBD30 (diesel 70%, microalgae biodiesel 30%) and MBD35 (diesel 65%, microalgae biodiesel 35%), respectively. Prepared blend performance analysis is done on single-cylinder 4-stroke, diesel engine test rig. Experiment reveals that 1 kg dry algae is obtained from 15 kg of green grown microalgae and 2 kg of dry microalgae powder is given 250 ml of crude algae oil. BTE is obtained as 32.11% for MBD0, 31.48% for MBD10, 30.83% for MBD15, 30.21% for MBD20, 29.47% for MBD25, 28.64% for MBD30 and 27.58% for MBD35 at maximum loading. Finally, significant decrement is found in hydrocarbon (HC) and sulphur oxides (SOx) emissions as compared to diesel with increase in load.KeywordsSoxhlet apparatusMicroalgae biodieselTransesterificationDifferent biodiesel blendsPerformance analysis
