Abstract
Biodiesel production in the world needs new and more efficient production methodologies. The main producers of biodiesel in the world carry out the process in the conventional way, although several researchers have identified that the organic reactions produced by heating of the irradiation with microwaves, present reduced times, and similar yields than the conventional process. In this way, the main goal of this work consists in the development of a methodology to produce a biodiesel-type biofuel by microwave irradiation, using national raw material (soybean oil), methyl alcohol and potassium hydroxide as catalyst. An experimental design was carried out with two control variables, oil:alcohol molar ratio, and reaction time. The results showed that all efficiencies were above of 95%. Highlighting 3 experiments, biodiesel 3, with oil:alcohol molar ratio 1:12 and transesterification time of 2 minutes, in which a mass efficiency of 100,69% was obtained, biodiesel 4, with oil:alcohol molar ratio 1:6 and transesterification time of 2 minutes, with a mass efficiency of 97.9%, and biodiesel 6, with an oil:alcohol molar ratio of 1:12 and transesterification time of 0.34 minutes with an efficiency of 100%. The latter being the most promising result of the present work, showing a higher conversion within the parameters required by regulatory standards of the oil with methyl esters in a short time. In addition, for the three mentioned biodiesels, their physicochemical properties were evaluated, in which they presented values within the limits allowed by the both national and international biodiesel standards. The gas chromatography mass spectrometry analysis (GC-MS) was also conducted, showing higher content of methyl esters. The energy analysis of biodiesel production using microwave irradiation technology was presented as well. In these conditions, it can be concluded that through the methodology developed in the present work it was possible to produce biodiesel with higher percentages of conversion to methyl esters, complying the standards for use in internal combustion engines.
