An ever-increasing drift of energy consumption, unequal geographical distribution of natural wealth and the quest for low carbon fuel for a cleaner environment are sparking the production and use of biodiesels in many countries around the globe. In this work, jatropha and karanja biodiesels were produced from the respective crude vegetable oils through transesterification, and the different phy...

BACKGROUND Temporal and spatial expression of fatty acid and lipid biosynthetic genes are associated with the accumulation of storage lipids in the seeds of oil plants. In jatropha (Jatropha curcas L.), a potential biofuel plant, the storage lipids are mainly synthesized and accumulated in the endosperm of seeds. Although the fatty acid and lipid biosynthetic genes in jatropha have been identif...

The revolution in industrialization throughout the world has boosted the utilization of machinery and shifted the muscle power to machines. The use of machines in various sectors has increased the demand of petroleum based lubricants. Lubricants act as an antifriction media, facilitating smoother working, reducing the risks of undesirable frequent failures and maintaining reliable machine opera...

The high demand to replace the petroleum fuel makes renewable and sustainable sources such as Palm oil, Jatropha oil and Algae as main focus feedstock for biodiesel production in Malaysia. There are many studies conducted on Palm oil and Jatropha oil, however, the use of Algae as an alternative fuel is still in its infancy. Malaysia already implemented B5 based Palm oil as a feedstock and this ...

In this study, Jatropha curcas oil was used as feedstock for biodiesel production by alkali-catalyzed methanolysis. To establish the optimum conditions for biodiesel production, effects of certain factors were investigated, these factors are oil-to-methanol molar ratios (1:4 1:8), KOH catalyst concentrations (0.5 1.5% w/w oil), reaction temperatures (50 70oC), and reaction times (55 90minutes)....

Esters of plant oils are preferred to parent oils if used as fuels in diesel engines because esterification reduces the viscosity of plant oils and makes it comparable to that of diesel. The present work mainly deals with the effect of storage time on the quality of plant oils and their esters with respect to mainly FFA content, viscosity and change in weight. The study was carried out for a pe...

B of fossil diesel with biodiesel is an important climate change mitigation strategy across the world. In 2003 the Planning Commission of India decided to introduce mandatory blending over increasingly larger parts of the country and reach countrywide 30% blending status by the year 2020 and opted for nonedible oilseed species of Jatropha curcus raised over lands unsuited to agriculture as it w...

One of important sources of biomass-based fuel is Jatropha curcas L. Great attention is paid to the biofuel produced from the oil extracted from the Jatropha curcas L. seeds. A mechanised extraction is the most efficient and feasible method for oil extraction for small-scale farmers but there is a need to extract oil in more efficient manner which would increase the labour productivity, decreas...
