ABSTRACT
Latin America has considerable potential in the production of biomass, mainly for the use of its waste, Brazil being one of the most important representatives in the generation of energy from these renewable sources. In this sense, the paper approaches eucalyptus biomass, in the form of residue, as a promising source of low cost for the production of energy and chemical products. The objective of this work is to perform the fast pyrolysis at 500 °C in the presence of mesoporous Al-MCM-41 catalyst to evaluate the performance of the phases (bio-oil, biogas and bio-coal), as well as to analyze the products generated in the liquid phase using a gas chromatograph with a coupled mass spectrometer. The catalysts and the biomass were characterized by scanning electron microscopy (SEM) and X-ray fluorescence (FRX). Elemental analysis, immediate analysis, calorific value and thermogravimetric analysis were performed for eucalyptus. Bio-oil, bio-gas and bio-carbon yields were obtained, compatible with the literature, besides proving that the presence of the catalyst influences directly in this distribution. The main compounds identified were acetic acid, 1-hydroxy-2-propanone, 1-1-diethoxyethane, furfural, confirming the importance of the process for obtaining chemical products.
