Abstract Methyl ester biodiesel was produced from Moringa Oleifera oil and Jatropha Curcas oil with the sole aim of assessing the feasibility of the feedstocks as viable sources of biodiesel in Botswana. Oil extraction and transesterification were carried out under identical experimental conditions for both Jatropha Curcas and Moringa Oleifera biomass. Oil was extracted from seeds through a soxhlet extraction method using the solvent, n-hexane. The extracted oil was then trans-esterified at 60 °C using a methanol/oil ratio of 12:1 at a stirring rate of 350 rpm, 3 wt. % catalyst loading and 120

Biodiesel obtained from vegetable oils as an alternative fuel for diesel engine is becoming increasingly important. The biodiesel quality and yield are affected by the properties of the oil used. The properties of the oil vary from region to region depending on the nature of the soil in which oil crops are cultivated, agricultural practices, rainfall etc. In this study the raw oil from Jatropha Curcas seeds grown in the western Ghat section of South India was tested for its physiochemical properties to determine its suitability for biodiesel production. A bench scale, compact biodiesel process

The importance of diesel fuel in Indian context is very different from that in the developed countries. Diesel is being used in mechanized agricultural, public transportation sector and also for several other applications. In the wake of the present fuel crisis, it has become essential to identify some renewable and environmentally compatible substitutes to diesel fuel. In the present investigation the high viscosity of the Jatropha curcas oil which has been considered as a potential alternative fuel for the diesel engine was decreased by transesterification (methanolysis) and blending the met

This paper investigated the three critical reaction parameters including catalyst concentration, microwave exit power and reaction time for the transesterification process of jatropha curcas oil using microwave irradiation. The work is an attempt to reduce the production cost of biodiesel. Similar quantities of methanol to oil molar ratio 6:1 and calcium oxide as a heterogeneous catalyst were used. The results showed that the best yield percentage 96% was obtained using 300W microwave exit power, 8 %wt CaO and 7 min. The methyl ester FAME obtained was within the standard of biodiesel fuel.

Biodiesel has attracted considerable attention during the past decade as a renewable, biodegradable, and nontoxic fuel alternative to fossil fuels. Biodiesel can be obtained from vegetable oils (both edible and non-edible) and from animal fat. Biodiesel was produced through esterification of Jatropha oil using an alkaline catalyst. The process was carried out at the reaction temperatures of 63 and 55°C, with a 6:1-11:1 oil to methanol molar ratio, and the concentration was verified. In this research work, a yield of 91.78% and 80% was achieved. Furthermore, the flash point of 129.1°C obtained

Sudan is highly dependent on diesel. Diesel is used in agriculture machines, transportation, and other applications. This study has been carried out to produced biodiesel from Jatropha curcas seed oil. Jatropha was chosen because it is not edible, therefore it will not pose a new problem to humans regarding food competition. This research successfully extracted oil from Jatropha curcas seed using n-hexane solvent with yield 39%. The oil than converted to biodiesel by alkaline transesterification process with a conversion yield 92 %. The properties such as flash point, acid value, viscosity, io

Ce produit présente plusieurs avantages sur les autres huiles végétales comme l'huile de palme ou l'huile de colza, qui recommandent sa production et son utilisation. En effet, la plante de Jatropha Curcas peut être cultivée sur des sols pauvres à faibles précipitations, évitant ainsi d'utiliser des sols plus fertiles pour sa culture permettant ainsi aux petits exploitants de réserver leurs terres aux cultures de base.

The major technical problems associated with the use of biodiesel in large proportions are (i) more prone to oxidation which can cause the fuel to become acidic and to form insoluble gums and sediments that can plug fuel filters, (ii) cold flow properties and (iii) higher NOx emissions compared to diesel fueled engines. It is reported that addition of antioxidants, emulsifying water with biodiesel, addition of fuel with high latent heat of vaporization, and low cetane fuel can reduce the NOx emissions in biodiesel fueled engines. Addition of antioxidants to biodiesel can improve both the

Biodiesel is a renewable alternative biofuel and is an option to diversify the conventional fossil fuels. Moreover, biodiesel is nontoxic, biodegradable, and biomass renewable diesel fuel and its combustion produces low amount of CO, CO2, hydrocarbon, and particulate matter. It can be produced through transesterification reaction. The most common method is homogeneous transesterification process using basic catalyst as NaOH. However, this route has drawbacks as long timespans, saponification reaction, a large amount of solvent, and a large amount of water to neutralize the methyl esters to eli

Increasing strict regulation on the sulfur content of diesel fuels results in decreases the lubricity of these fuels. The lubricity of the fuel is an indication of the amount of wear or scarring that occurs between two metal parts covered with the fuel as they come in contact with each other. Low lubricity fuel may cause high wear and scarring and high lubricity fuel may provide reduced wear and longer component life. Previous studies have shown that alkyl esters of triglycerides derived from vegetable oils have increased diesel fuel lubricity at concentration of less than 1%. The major object
