Abstract

Biodiesel produced by transesterification of triglycerides with alcohol, is the newest form of energy that has attracted the attention of many researches due to various advantages associated with its usages. Response surface methodology, based on a three level, three independent variables central composite design is used to analyze the interaction effect of the transesterification reaction variables in the experiment which consists of temperature, molar ratio of methanol to oil and catalyst concentration on biodiesel yield. The linear terms of methanol molar ratio, and also the quadratic terms methanol to oil ratio and temperature, had significant effects on the biodiesel production (p<0.05). Through optimization plot done in response surface design method, maximum yield for the production of methyl esters from corn oil was predicted to be 90.15 % under the condition of temperature of 50.85oC, the molar ratio of methanol to corn oil of 7:1, and catalyst concentration of 0.722 wt%, with a fixed constant variable of stirring speed 300 rpm and a reaction time of 1hr.
