BACKGROUND Jatropha curcas is recognized as a new energy crop due to the presence of the high amount of oil in its seeds that can be converted into biodiesel. The quality and performance of the biodiesel depends on the chemical composition of the fatty acids present in the oil. The fatty acids profile of the oil has a direct impact on ignition quality, heat of combustion and oxidative stability...
In the present study, jatropha oil cake (JOC), a waste produced from processing jatropha seeds for biodiesel production, has been investigated for the removal of nickel (II) from aqueous solutions. Jatropha oil cake contains different functional groups that can participate in the metal ion complexation. Jatropha oil cake is used in its natural form (JOCN) as well as in its immobilized form (JOC...
For determining the oil content, seed and fruit characteristics of Ethiopian Jatropha provenances, the study was conducted in five regions of Ethiopia namely Southern Nation Nationalities Peoples Regional state, Amhara region, Tigria region, Oromia region and Benishangul Gumuz Regions, where Jatropha is found abundantly. A total of 23 Zones, 36 Weredas and 40 sampling sites were considered from...

Jatropha curcas L. is one of the seed plants that have lipase activity and can work well in hydrolysis reactions chemical synthesis. This study aims to determine reacts with castor oil organic solvents. In this research, solvents, especially hydrophobic were used reaction increase lipase's catalytic activity. The solvent has a hydrophobicity level between 2 4, namely hexane. research stages con...
This paper presents a pre-mixed combustion model for diesel and Jatropha oil blends combustion studies. Jatropha oil blends are considered as a mixture of diesel and Jatropha oil. CFD package, FLUENT 6.3 is used for modeling the complex combustion phenomenon in compression ignition engine. The experiments are carried out on a single cylinder, four strokes, water cooled direct injection compress...
Jatropha curcas has a variety of uses which are of great economic significance. Jatropha oil can be used as fuel alternative and for making biodiesel that is supposed to overcome the source limitation problem. In this study, conventional, ultrasound assisted and microwave pretreatment solid liquid extraction of Jatropha seed were studied in terms of amount and quality of the extracted oil. The ...
