Supercritical reactive extraction for Jatropha curcas L. seed was demonstrated to be a viable process for biodiesel production process with high yield and the elimination of separate extraction step. However, because the solid seeds were reacted directly and susceptible to impurities...

Biodiesel production by non-catalytic supercritical methyl acetate (SCMA) reaction has been developed and optimized in previous study using Jatropha oil as oil feedstock. The reaction produces fatty methyl acid esters (FAME) as well as triacetin as the co-product. Due to the requirement of high...

In a bid to increase the cost competitiveness of biodiesel production against mineral diesel, process intensification has been studied for numerous biodiesel processing technologies. Subsequently, reactive extraction or in situ transesterification is actively being explored in which the solid...

In this review, recent development of glycerol-free supercritical fluid transesterification for biodiesel production was discussed. Glycerol-free supercritical fluid processes including single-step and two-step transesterification for biodiesel production were reviewed and subsequently the...

Cultivating microalgae at industrial scale for biodiesel production required substantial amount of mineral fertilizer, typically nitrogen and phosphorus. In fact, the production of mineral fertilizer implies the usage of energy and fossil fuels resulting to unsustainable practise in a long term....

Biodiesel is a good alternative fuel to petroleum diesel. It is produced through transesterification reaction between vegetable oil or animal fats and alcohol. The process faces various problems related to the immiscible nature of the reactants causing poor mass transfer rate. This drawback is...
