“…The species has many common names in different regions such as the physic nut, barbados nut, curcas bean, purging nut, and jatropha [1], and the name jatropha is frequently used to refer to the species [2,3]. Jatropha (J. curcas L.) is a semievergreen perennial tree or shrub, which can reach a height of 3 to 6 m, but it can attain a height of 8-10 m under favorable conditions [4]. It is native to Central America and has naturalized in many tropical and sub-tropical areas including Asia, Africa, and North America [5].…”

“…It is native to Central America and has naturalized in many tropical and sub-tropical areas including Asia, Africa, and North America [5]. Originating in the Caribbean, jatropha has been spread as a useful hedge plant to Africa and Asia by Portuguese merchant, and now the plant is found abundantly in many tropical and sub-tropical regions of the world [4,5].…”

Effects of Different Extraction Solvents on Oil Extracted from Jatropha Seeds and the Potential of Seed Residues as a Heat Provider

The present study focuses on the determination of oil contents of thirteen different jatropha seed collections from Ethiopia. The oil was extracted with a Soxhlet extractor using n-hexane which was selected out of four different solvents: diethyl ether, ethanol, n-heptane, and n-hexane. Cotton and thimble were used as filter for the extractions. Some properties of the oil of Chali seed collection and a sample of mixed oils (a mixture of equal volume of oils from thirteen different seed collections) were determined. The energy contents of selected de-oiled jatropha seed residues were also estimated. In the extraction with cotton and thimble, the largest percentage of oil yield was obtained from Dana seed (48.29%) and Chali seed (45.79) collections, respectively. The acid value (1.32 mg KOH/g) and percentage of free fatty acids (%FFA) (0.66%) of Chali seed oil were lower than the acid value (2.12 mg KOH/g) and %FFA (1.06%) of the mixed oil, and thus, the former oil is more suitable for alkaline-catalyzed biodiesel production. The iodine values of both Chali seed oil (116.02 g/100 g) and mixed oil (109.24 g/100 g) did not exceed the maximum standard for biodiesel according to the European EN 14214 specification, and the oils could be used for biodiesel production. The gross calorific values of de-oiled jatropha seed residues after oil extraction were found to range from 18.57 to 24.03 MJ/kg, and with the average value of 19.64 MJ/kg. Thus, the de-oiled seed residues can be used as the source of heat.
