RESUMO:

The field of renewable energies has attracted much interest from world-wide research because of the need to minimize damage to the environment and reduce dependence on fossil fuel energy. Biodiesel has established itself as a promising source of renewable and substitute energy for oil and diesel because of its high energy, biodegradable and "clean burning". The interesterification with methyl acetate is a new technique and has the advantage of producing, in addition to methyl esters (biodiesel), triacetin (product of great market value). Supercritical technology enables the production of biodiesel without the presence of catalysts, eliminating the need for further purification processes. The sesame (Sesamum Inducum L.) is one of the oldest oilseeds used by mankind (from 4300 BC). Its seeds provide a large amount of unsaturated fatty acids, especially oleic (from 35.9 to 42.3%) and linoleic (from 41.5 to 47.9%). Thus, the present work seeks to analyze the viability of biodiesel production through the reaction of non-catalytic interesterification of sesame oil with methyl acetate under supercritical conditions, the oil yield, the parameters that influence the reaction (oil / acetate molar ratio of methyl, pressure and operating temperature, ...) and the optimum conditions using this technique.
