Identification of significant parameters for the production of Jatropha biodiesel using preliminary experimentation

Sunil Dhingra


The current research work is on Jatropha biodiesel for finding the significant parameters in optimum biodiesel yield. The one factor at a time approach is applied in the esterification. The trans-esterification reaction is used by mixing of Jatropha oil and ethanol in the presence of catalyst KOH. After some time two products are formed a Jatropha biodiesel and a glycerin. The density of glycerin is more as compared to biodiesel. Hence it is settle down in the beaker. The biodiesel is separate apart and cool down in another beaker. The water bath is then used to cool down the temperature of produced biodiesel. During the trans-esterification process it has been found from literature review that five process parameters are affecting the biodiesel yield which are ethanol to oil molar ratio, reaction temperature, reaction time, catalyst concentration and rpm of magnetic stirrer. It is observed from preliminary investigation that all the parameters are affecting the biodiesel yield as any one input parameter is increased and other four remains at constant value
