Abstract

Biofuel is a renewable source of energy and reduce dependence on fossil fuels. Alternatives to make it more attractive and economically viable biofuels have become of great interest for researchers. Then biodiesel production, which is a biofuel obtained from a fatty materials (vegetable or animal source) together with a short chain alcohol, has been explored. Alternatives to make it more accessible production for cost and sustainable led to use of the free fatty acid (FFA), which has been distillated of soybean oil and ethanol as alcohol, since Brazil is self-sustaining in ethanol to the reaction for obtaining biodiesel by esterification. The aims of this work were the production of fatty acids ethyl esters (biodiesel) through the conversion of free fatty acids from distillation of soybean oil batch reactor, using ethanol 96 °GL for the esterification reaction, using Amberlyst® 15 resin as heterogeneous catalyst. The variables studied were temperature, molar ratio of FFA: ethanol and catalyst concentration. The condition that presented the best conversion was 90 ° C temperature, molar ratio FFA: ethanol 1: 5 and 3% catalyst, obtaining a conversion of 28.92%. Thus, new conditions involving the variables should be investigated in order to obtain a better conversion.
