Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions transesterification and esterification. This involves vegetable or animal fats and oils being reacted with short-chain alcohols (typically methanol or ethanol). The alcohols used should be of low molecular weight, ethanol being one of the most used for its low cost. However, greater conversions into biodiesel can
The vitality of a technology or its product depends mainly on its technological advancement, economic efficiency, the urgency of market demand and the intervention of government policies, and in most cases, these conditions are indispensable. The same is true for biodiesel. Technical aspects: As mentioned earlier, the production technology of biodiesel has been developed for
Jatropha curcas is originally a medicinal plant. Recently, it has been found that its seeds contain high oil content. It is one of the most studied energy plants in the world which can produce biodiesel. Jatropha curcas has high economic value and is recognized as a bioenergy tree in the world. Its seed kernel is
Present situation the international petroleum energy market is in short supply. World oil supply constraints have led to soaring international oil prices: oil prices climbed to $40 a barrel in 2003; to $50 a barrel in June 2004; to $60 a barrel in September 2005; to $70 a barrel in April 2006; and to the
