RESUMO:

With an increasing demand for liquid fuels, it is important to research and develop environmentally friendly alternatives. The aviation industry requires a type of fuel that requires specific properties, where alternatives, such as aviation biofuel, must be compatible with existing engines. Biofuel can be synthesized in a number of ways, including thermal pyrolysis and thermo-catalytic pyrolysis. Thus, this paper aims to obtain aviation biofuel from Licuri oil by catalytic pyrolysis in the presence of a mesoporous catalyst. Therefore, the synthesis and characterization of AlSBA-15, as well as impregnation of the catalyst with Nickel (Ni) in percentages of 1%, 5% and 10% by mass were studied. The catalyst was characterized by thermal analysis TG / DTG, X-ray diffraction (XRD), Fourier-Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM / EDS). The catalysts showed XRD reflections consistent with the hexagonal P6mm structure of the SBA-15, demonstrating that the molecular sieve remained structured even with the impregnation of the metals. TG / DTG thermal analysis shows loss of mass compatible with loss of water and elimination of structure directing agent efficiently. Kinetic study was performed from the TG / DTG analysis using the KAS and Vyazovkin model.
