Frontiers - Current Progress of Jatropha Curcas
This article looks at the national and global actors, social networks, and narratives that have influenced Jatrophas worldwide acceptability as a biofuel crop. Jatropha Curcas is a genus of around 175 succulent shrubs and trees in the Euphorbiaceae family (some of which are deciduous, such as Jatropha Curcas L.). Its a drought-tolerant perennial that thrives in poor or marginal soil and

SingleÛåstep ultrasonic synthesis of biodiesel from crude
Statistical optimization of the process shows 93% yield for 8.5 wt % catalyst, 20:1 alcohol to oil molar ratio and temperature of 333 K. Peculiar feature of this process is that high yield is seen at moderate temperature and molar ratio, which are much smaller than that for conventional sulfuric acid catalyzed processes.

Oil is typically extracted using cold press or a mechanical expeller. Steam may be used during the process to maximize the recovery. A high-quality oil is one without any free fatty acids (FFA). It is not unusual to find up to 15% FFAs in crude Jatropha oil, which can be brought to

The viscosity of crude oil is then decreased near to conventional diesel to make it preferable for use in diesel engine and thus determine the performance of engine with proposed fuels. In this study, viscosity was decreased by (i) preheating oil (Jatropha oil) and (ii) by blending Jatropha methyl ester with diesel.

Optimization and kinetic study of biodiesel production
In this study, the conversion of crude Jatropha curcas oil into biodiesel through transesterification was investigated in the presence of heterogeneous solid catalysts under supercritical methanol environment. The principal impetuses catalyzing the expansion in optimal biodiesel production are primarily attributed to the increasing demand for sustainable energy sources, the availability of raw

For example, a novel method using a pulsed loop reactor has been developed for a more effective transesterification reaction of Jatropha crude oil (JCO) to J. curcas methyl ester (biodiesel) [102]. In addition, the nation is concentrating on improving the oil yield per hectare rather than expanding Jatropha plantations due to the disadvantage of high land acquisition cost in the country [14] .

Crude unrefined jatropha oil was dark greenish yellow in color. The fatty acid profile of jatropha oil is given in Table 1.Its FFA content was determined by standard titrimetry method [10].This oil had an initial acid value of 28©I1 mg KOH g ?1 corresponding to a FFA level of 14©I0.5%, which is far above the 1% limit for satisfactory transesterification reaction using alkaline catalyst.
