The production is carried out by pyrolysis of biomass at different temperatures, between 300 and 500 degrees C. In this study, the corn cob pyrolysis was investigated using thermogravimetric analysis (TGA) and Fourier Transform Infrared Spectroscopy (FTIR). Samples after pyrolysis were compared with raw biomass to evaluate changes in fuel characteristics. In DTG curves a reduction in the number of degradation peaks in the carbonized material was observed. The FTIR spectra allowed to identify the aromatic ring of the lignin in the charcoals structure, indicating the presence of this compound even in charcoals produced with a temperature of 500 degrees C. It can be concluded that the temperature of 400 degrees C was enough to completely degrade the hemicellulose and cellulose of the biomass, resulting the final product (charcoal) less reactive or thermally more resistant than the in natura corn cob.566-569engthermal degradationbiomasscharcoalArtigo10.21577/0100-4042.20170360S0100-40422019004500566WOS:000476472900011Acesso abertoS0100-40422019004500566.pdf
