RESUMO:

A demand for fossil fuels is high worldwide, generating large environmental impacts in its extraction and burning. Another factor that becomes notorious and discarded of household waste is no environment adding ecological damage. From two pillars, it is necessary to use renewable resources with regard to biomass of residual vegetable oils. Therefore, this work offers purposes to obtain renewable fuels through pyrolysis in the presence of mesoporous catalysts. As biomass listed for the oil work of aquatic Pachira, commonly called munguba, and frying oil, its reuse is necessary for reuse in fuel sources. As a catalyst, it was used as mesoporous molecular sieves, KIT-6 and MoKIT-6. The catalysts were characterization by X-Ray Diffraction, Thermal Analysis (TG / DTG), Electron Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR) and X-ray Dispersion Spectroscopy (EDX). Over time, the structuring of the crystals of the standard KIT-6 and MoKIT-6, this one presents an oxide phase of Molybdenum (TG / DTG), a physical structure of the KIT-6 crystals. (MoO₃) at the catalyst surface and percent proposed was successfully ratified in the EDX descriptions. In the kinetic study, it was evidenced that in the frying oil there was an evident action of MoKIT-6, obtaining practically linear during the conversion, obtaining inferior energies of activation. To obtain the renewable hydrocarbons, the biomasses were submitted to thermal and thermo-catalytic pyrolysis and the product obtained was analyzed by: GC-MS, viscosity, specific mass, acid number. In summary, it can be concluded that all the specific characterization of KIT-6 and its functionalized form MoKIT-6 were obtained within the planned, and the frying oil could be successfully converted and bio- oil with excellent characteristics for use as fuels.
