Abstract

The search for alternative source of energy has become important as many believe that fossil fuel is not going to last for long and it is time to change to renewable source of energy. Biodiesel, produced from vegetable oil and alcohol commonly through the process of transesterification has become the most reliable biofuel that is widely used in the world today (Okullo, Temu and Ntalikwa, 2010). The reaction kinetic model for the biodiesel has been developed in the past years with limitation of specific reactions for each model. There is need to study and obtain generalized reaction kinetic model that can be used for all the reactions involved in the biodiesel production. This study is about developing general reaction kinetic model for all the reactions involved in the biodiesel production using simulation software called MATLAB by the means of OPTIMIZATION TOOLBOX to obtain the optimum kinetic data which will be compared to the experimental data for accuracy. The optimized value of activation energy and the pre-exponential factor values are general values that can be used at any temperature to calculate the concentration of the product yield. This will enable to use the optimized values to calculate the rate constants at any temperature. A general kinetic model and parametric study of the kinetics of the reaction involved in the synthesis of biodiesel developed in this project through the use of MATLAB OPTIMIZATION TOOLBOX have shown promising results whereby it has the potential to yield the similar set of results as compared to experimental results. Despite the increase in concentration of glycerol and the rate constants, the methyl esters yielded at any temperature are similar to that of experimental results with minimal error below 5 %. The objective of this project is achieved.
