In pyrolysis of biomass process: solid, liquid and gas products are obtained. To optimize the organic material degradation, a variety of catalysts are employed. Morphological changes in the catalysts during the pyrolysis reaction are evaluated by Transmission Electron Microscopy (TEM) technique. In this work, a pore and pore wall sizes, before and after pyrolysis process, of a Cu/SBA-15 catalysts are characterized. From results it is observed that the catalyst not present morphological changes in the pyrolysis of biomass, indicating the possible re-use of catalyst in similar succesive processes
