RESUMO:
This research work was developed seeking the production of clean technologies and bioproducts with perspectives in industrial applications. For this purpose, several materials and bioproducts were obtained. The production of alternative silica (MP1) from the beach sand allowed to obtain mesoporous materials, MCM-41, as synthesized and modified, for several purposes, among these applications in CO2 adsorption processes, due to modifications with alkanolamines, MEA and DEA in addition to impregnation with metal cations, such as Ni+2, Zn+2 and Ag+, which allowed applications in deep desulphurization processes in petroleum derivatives. The chemical modification of MP1 with metals produced SKS bimetallic catalysts, successfully used in the synthesis of bioproducts such as biodiesel and biolubricants. All products were characterized by FTIR, TG / DTG, NMR, CG / MS, DRX, MEV-FEG, EDS, RANCIMAT, FRX, ICP-OES. Tests of reuse of the catalyst and studies on the conversion were carried out in order to obtain the best synthesis parameters. The bioproducts obtained obeyed the specifications of ANP 45/2014 for biodiesel and ANP 669/2017 for biolubricants. In order to optimize the use of the obtained bioproducts, natural antioxidants were obtained from the extracts of Syzygium aromaticum and Punica granatum and effectively tested in cotton biodiesel, to evaluate the effects produced in the oxidative stability of the biofuel.
