Produção de biodiesel a partir de subprodutos da agroindústria do pêssego

Abstract

In the canning industries of Pelotas-RS, tons of fruit are processed annually, especially the peach, where the seed of this fruit (stone) is discarded, where the almond with a high fatty acid content is contained. With the appearance of several studies for obtaining biodiesel, where the main raw material used is from soybean oil, in this work, the objective is to give a correct destination to the residue and also to make use of the residues generated in the processing of the peach in the canning industries, more precisely the peach kernel than through its almond with the extraction of oil, and so we proceed to the transesterification of peach oil. In this way, the determination of the ideal conditions for the production of biodiesel from vegetable oil from the peach kernel refined via methyl transesterification, using potassium hydroxide as a catalyst, carried out by means of an experimental design, using a 2³ factorial arrangement. With this, it is expected that through the evaluation of the physicochemical properties of the esters derived from the fatty acids of the oil produced, they fall within the norms established by the National Petroleum Agency - ANP and thus it is possible to use the generated waste, and that through of this process the industries can be energy self-sustainable.
