Synthesis and Calorific Value of Biodiesel by Methanolysis of Castor and Olive Oils in Admixture

Abstract

Abstract: Herein we report the methanolysis of castor oil and olive oil admixture to produce biodiesel. Four (4) parameters were investigated namely; temperature (45 oC-75 oC), reaction time (30 minutes- 150 minutes), methanol-to-oil molar ratio (5:1-15:1and castor oil-to- olive oil ratio (30:70, 45:55, 50:50 and 40:60). All reactions were done at a constant stirring rate of 400 rpm. The optimum values for the investigated parameters were found to be 60oC temperature, 6:1 molar ratio, 120 minute reaction time and 0.5 w/wt % NaOH. The results showed that 92% yield was achieved for 45:55% castor to olive oils composition. This yield was higher than biodiesel yield from either castor oil or olive oil.
