Production of Biodiesel from Castor Oil using acid and Base catalysts

Biodiesel defined as the mono alkyl ester of vegetables oils or animal fats is an “alternative” diesel fuel that is becoming accepted in steadily growing numbers of countries around the world. As biodiesel comes from domestically produced renewable resources, it contributes to the domestic energy security. Biodiesel is simple to use, biodegradable, nontoxic, and essentially free of sulfur and aromatics. In this work, it is planned to produce methyl ester fuels based on non edible oils like castor oil by using different catalysts like NaOH and H 2SO 4. The effect of various parameters like temp, residence time, catalyst concentration investigated on yield of biodiesel and physical properties like Viscosity, Specific gravity, Acid value.
