Due to increase in demand of petroleum products, the prices of petrol and diesel are increasing all over the world. As the available resources of fossil fuel are depleting at faster rate and by 2025 ,the world may face a severe crisis of petroleum fuels, hence an alternative sources of energy to replace fossil fuels are being explored worldwide. Biodiesel is one of the promising biofuels and an alternative for fossil fuels as a primary energy source for machineries and vehicles. It is defined as the mono alkyl ester of vegetables oils or animal fats. Due to its technical feasibility and nonpolluting characteristics, biodiesel is gaining acceptance in steadily growing numbers of countries around the world. Biodiesel is biodegradable, nontoxic, and essentially free of sulfur and aromatics. In this work, experimental investigation has been carried out to produce methyl ester fuels based on non-edible oils like castor oil by using different catalysts like NaOH and H2SO4. The parameters such as temperature, residence time has significant effect on yield of biodiesel and physical properties like Viscosity, Specific gravity, Acid value. In this research the effect of acid and base catalysts was studied on yield of biodiesel and physical properties like viscosity, Specific gravity, Acid value
