“…This is a non-edible oil-bearing plant widespread in arid, semi-arid, and tropical regions of the world. Jatropha is a droughtresistant perennial tree that grows in marginal lands and can live for over 50 years [26]. The oil content in jatropha seed is reported to be in the range of30 to 50% by weight of the seed and ranges from 45 to 60% by weight of the kernel itself [26].…”

The oil content in jatropha seed is reported to be in the range of30 to 50% by weight of the seed and ranges from 45 to 60% by weight of the kernel itself [26]. The jatropha tree has several beneficial properties: its stem can be used as a natural tooth paste and brush; latex from the stem can be used as a natural pesticide and for wound healing; and its leaf can be used as feed for silkworms, among other uses.…”

Vegetable oils and their methyl/ethyl esters are alternative renewable fuels for compression ignition engines. Asian countries are not self-sufficient in edible oil and are exploring non-edible seed oils, like jatropha and castor as biodiesel raw materials. In the present study jatropha and castor oil were used for the preparation of biodiesel by the transesterification process. Diesel and jatropha oil methyl ester (JOME) blends were used to conduct short-term engine performance tests at varying loads. Similar tests were conducted with castor oil methyl ester (COME). The engine parameters were recorded and compared for the prepared blends. The best engine operating condition based on lower brake specific fuel consumption and higher brake thermal efficiency were identified and compared. The maximum thermal efficiency was observed at 13% substitution of COME in diesel and 18% for JOME in diesel. An analysis of variance test was applied to the observed data for both the fuels. Results indicated for COME, F = 2.397, that there is no significant effect on fuel consumption with the fuel type. There is a significant effect on fuel consumption and thermal efficiency with % of load. For F = 5.69 there is a significant effect on thermal efficiency with the fuel type. Similar trends were observed with JOME blends. These trends indicated that blends in the ratio of 0-20% by volume of biodiesel can be added to neat diesel without any change in the hardware of the engine.

“…From the previous study, by using biodiesel like Jatropha plant, it could reduce global warming and provide a clean air. Jatropha oil can be produce worldwide because of its potential [7]. Oil can be produced up to 40% from its seeds and also the properties of the oil is better compared to soybean oil and palm oil [8].…”

Nanostructure and oxidation properties investigation of engine using Jatropha biodiesel as engine fuel

Abstract. The purpose of this study is to investigate the soot nanostructure characteristic and soot oxidation behaviour that is emitted from a single cylinder diesel engine by using two different engine fuels that is Jatropha Biodiesel (JBD) with the presence of 3% of methanol as additive and Diesel fuel. In order to obtain the result for soot characteristic, Scanning Electron Microscope (SEM) is used, while Thermogravimetric Analysis (TGA) is used to analyze the oxidation of the soot itself. The parameter for the engine testing has been fixed by applying different loads of 25% and 50% load with constant speed of 2500 rpm. The result has been compared for each fuel in terms of their structure and oxidation behaviour. The soot was collected on a filter paper and the SEM grid from the exhaust stream within the time period set. The soot is then observed by using SEM and the result shows that diesel soot particulate matter is smaller with average size of 95 nm for 25% load and 63.5 nm for 50% load than those of B20, which has the average size of 122 nm for 25% load and 105 nm for 50%. It complies with the evidence that stated 11% of the oxygen content helps in lowering particulate emission by improving the combustion. The result also shows that the oxidation behaviour of B20 occurs faster than diesel either at 25% load or 50% load.

“…curcas L. (Euphorbiaceae) is a small tree or shrub with a life span of about 50 years [23]. It has oily seeds, which are considered as a feedstock for biodiesel production and, as such, a considerable promise for a bio-based economy [23][24][25][26]. According to Brittaine and Lutaladio [27] and Nassiré Derra et al [28], J. curcas is believed to have been spread in the sixteenth century by Portuguese seafarers from its center of origin in Central America and Mexico via Cape Verde and Guinea Bissau (West Africa) to other countries in Africa and Asia.…”

Biofuel plants such as Jatropha curcas L. have potential to support the livelihoods of rural communities and contribute to sustainable rural development in Africa, if risks and uncertainties are minimized. Yet, recent papers have warned of the risk of biological invasions in such tropical regions as a consequence of the introduction of exotic biofuel crops. We investigated the seed dispersal risk and invasiveness potential of both J. curcas monoculture plantations and live fences into adjacent cultivated and uncultivated land use systems in Sissili province, Burkina Faso. Invasiveness potential was assessed through (i) detecting evidence of natural regeneration in perimeters around J. curcas plantations and live fences, (ii) assessing seed dispersal mechanisms, and (iii) assessing seedling establishment potential through in situ direct seed sowing. Spontaneous regeneration around the plantation perimeters of the three sites was very low. Individual seedling density around J. curcas live fences was less than 0.01 m −2 in all sites. Seventy percent of the seedlings were found close to the live fence and most of them derived from the same year (96 %), which indicates low seed-bank longevity and seedling survival. J. curcas can be dispersed by small mammals and arthropods, particularly rodents and ants. In some sites, such as in Onliassan, high secondary seed dispersal by animals (up to 98 %) was recorded. There were highly significant differences in germination rates between seeds at the soil surface (11 %) and those buried artificially at 1-2-cm depth (64 %). In conclusion, we failed to find convincing evidence of the spreading of J. curcas or any significant impact on the surrounding environment.
