An effective kinetic modelling for catalyst preparation process of biodiesel preparation experiments has been proposed in this study. Development of kinetic modelling for catalyst synthesis process is verified by two sample examples like calcination of raw eggshells and calcination of calcium aluminate (Impregnation of alumina (Al2O3) with calcined eggshells). Development of kinetic modelling for catalyst synthesis process of biodiesel production experiments will be more useful to determine at what rate the catalyst decomposition takes place during its preparation. Identification of reaction rate constant in prior will be more helpful in determining the selectivity of the catalyst chosen. It is observed from this study that for any catalyst synthesis process of biodiesel preparation experiments a complete kinetic modelling can be derived easily as proposed.
