Composite approach of RSM-ABO for optimization of production of Ricinus Communis biodiesel using Lithium doped CaO Nanocatalyst
The environment degradation and scarce fossil fuel reserves lead the scientists to look for new alternative renewable green sources of energy. Biodiesel has emerged out to be one of the most established and abundantly available renewable alternative fuel to which whole world is looking at. In the current research a new dual optimization approach of combined Response surface methodology and African buffalo optimization technique has been implemented successfully to optimize the biodiesel yield from Ricinus Communis (castor oil). For production of biodiesel a new catalyst development process has been devised. For rigorous intensification of the solution mixing, ultrasonication has been used instead of conventional magnetic stirrer or mechanical stirrer-based transesterification. High biodiesel yield of 74% was obtained using RSM alone which was enhanced to 90.25% using RSM -ABO methodology. The optimum parameters suggested by RSM-ABO for the maximum yield are 15:1 Alcohol to oil molar ratio, 3.5% catalyst weight, 65 deg C temp. and 65% amplitude in a reaction time of 42 minutes. It was observed that Lithium doped catalyst sourced from Musa root ash can be good renewable alternate for performing Ultrasonic transesterification of castor oil successfully. African buffalo optimization has been used probably for the first time to perform optimization of production of biodiesel from Castor oil.
