Application of Cocos nucifera L and its efficiency in production of biodiesel

Transesterification of vegetable oils, which is coconut oil, is carried out by using methanol and potassium hydroxide as catalyst. Methyl ester of vegetable oils or biodiesel have several outstanding advantages among any other renewable and clean engine furl alternatives and can be used in any diesel engine without modification. The most important variables affecting the methylester yield during the transesterification reaction are molar ratio of alcohol to vegetable oil and reaction temperature. All vegetable oils are more viscous, while the methyl esters of vegetable oils are slightly more viscous. Biodiesel has become more attractive because of its environmental benefits. The cost of biodiesel, however is the main obstacle to commercial. With cooking oil as a raw material, viability of a continuous transesterification process and recovery of high quality glycerol as a biodiesel by-product are primary options to be considered to lower the cost of biodiesel. In transesterification the reaction time is 24 hours for settling process. Viscosity of vegetable oils is 43.3 mm2/s get reduced in vegetable oil methyl esters at 4.5mm2/s and B20 is 6.3 mm2/s. A slightly decrease in density from 0.903g/ml to 0.765 g/ml for vegetable oil methyl esters decrease the viscosity from 43.3mm to 4.5mm2/s
