Production of Biodiesel from Castor Oil with its Performance and Emission Test

With increase in the demand of petroleum products the prices of petrol& diesel are increasing worldwide. Hence alternative sources of energy for running our generators, automobiles etc. are being considered worldwide. Both the edible and non-edible vegetable oils can be used as the raw materials for the biodiesel. Industrially, the most common method for biodiesel production is a basic homogeneous reaction. It is usually produced by a transesterification reaction of vegetable or waste oil with alcohol, such as ethanol and methanol. Diesel and Castor oil methyl ester (Diesel, B25, B50, B75, B100) fuel blends are used for conducting the performance and emission in terms of load increments from no load to full load. The bio- diesel can be used as 25 % blend with petroleum diesel in existing engines without any modification. The objective of this study is to compare the engine performance and emission results of biodiesel derived from used castor oil when applied in different proportions in engines.
