The technology of the extraction process of jatropha oil from its seeds using a solvent extraction technique was studied. The extraction process was carried out at room temperature using solvent-to-solid ratios ranging from 2 to 5 L/kg in a single and two successive stages. The results showed that a certain oil recovery of about 65% can be achieved using 5 m3 hexane for each ton jatropha seeds extracted in a single stage. This amount of solvent can be reduced to 2 m3/ton if the process is carried out in two successive stages. The composition of solvent and solid phases at equilibrium has been determined. Based on the equilibrium data, the partition coefficient or distribution ratio, D, between two phases was estimated. Also, the number of extraction stages necessary to achieve a certain degree of oil recovery has been investigated using different hexane-to-meal ratios.
