Prospect of algal biodiesel as a fuel in engine

Abstract

The fossil fuel consumption has been swiftly increase by the robust industrialization and increasing living standard of society. So the biodiesel fuel becomes more popular material among the research for get ride over these problems because it is green fuel, sustainable and renewable. A microalga is the fastest growing species with high oil cosntents (up to 60%). In organic solvent extraction method, polar (methanol) and non-polar (hexane) solvents are preferred for oil extraction. GLC technique is used for esterification and seventeen forms of fatty acids are identified. A large amount of Cis-11-eicosanoic acid (41.80%) is found in algae oil. Different catalysts i.e. NaOH, CaO (Egg Shell), and H2SO4, with methanol is used for biodiesel preparation. The fuel properties are premeditated for blends i.e. B10, B20, B30, B50 and B100 as per standards. Pure biodiesel attributes like density, kinematic viscosity they are within biodiesel standards. Many researches pragmatic that these physicochemical properties of biodiesel has great influence on engine performance, so this article provides guidance for examine the behaviour of biodiesel in engine based upon their physiochemical properties.
