Characterization and establishment of algae as an alternate green fuel

Abstract

quotNeed of energy is constantly increasing globally because of population and newlineindustrialization. Consumption of fossil fuel increases in pollution level and newlinecauses imbalance in the ecological level of the earth. So researcher has to think newlinefor alternative solution of fossil fuel. Biodiesel derived from crops may be newlinereplacement of petroleum-derived fuel used for transport and power generation newlinesectors without adversely affecting the crisis of food with keeping the newlineenvironment clean. Hence, the current research is introducing biodiesel production from algae (available in the entire world). Which is not a food in India, requires sunlight, CO, nutrients, waste / saline / blackish water and rocky/ waste land for the growth with the possibility of daily production. newlinePresent research talks about selection of suitable methods as per Indian newlinetechnological perception for algae cultivation, harvesting and biofuel conversion. newlineCharacterization of algae was carried out and compared with the available newlineresults of other feedstocks. Slow pyrolyser and fast pyrolyser were designed for newlineproduction of biodiesel. Algae biodiesel characterization was carried. The results newlinewere compared with ASTM D6751 standards and with the conventional fuel newlineused. Algae biodiesel satisfied all standards and BS-IV emission norms also. newlinePerformance tests on variable compression ratio research engine were carried newlineby varying % blending, engine load, compression ratio and injection pressure. newlinePredictive mathematical model was prepared using Response Surface newlineMethodology in MINITAB17 software and results were compared with newlineexperimental data for brake specific fuel consumption, brake thermal efficiency newlineand mechanical efficiency. newlineAbove research engine gives best performance with 100% blending, newlinecompression ratio of 18, injection pressure of 160bar and with full load condition newlinei.e. at 11kg.f with BSFC=0.28 kg/kW-hr , brake thermal efficiency = 31.51%. newlineExhaust gas analysis for B20, B40 and B100 was carried and compared with newlineexhaust gas emission standards BS-IV.
