Pirólise rápida de biomassa de eucalipto na presença de catalisador Al-MCM-41

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.
