Characterization of these charcoals was conducted using eight analytical methods. Each method describes specific changes in the temperature range until 1300 °C. Therefore, the combination of these methods provides comprehensive information on different pyrolysis stages. Fourier transform infrared (FTIR) spectroscopy, NMR spectroscopy, and thermogravimetry display changes until 700 °C. A prediction model for pyrolysis temperature until 800 °C is presented based on FTIR spectra with an R2 of 0.98. He-pycnometry resolves the temperature range between 500 and 890 °C. Small angle X-ray scattering (SAXS) describes precisely the evolution of the porous structure and completes the set of techniques by a description of the physical properties of the charcoal. X-ray diffraction (XRD) reveals the crystallographic change of the lignocellulosic structure toward precursors of graphite. The formation of calcite out of CaO and CO2 becomes evident.  aCharcoal  aPyrolysis  aCarvão  aMétodo de Análise1 aPREIMESBERGER, C.1 aPFEIFER, C.1 aSOLDO, D.1 aOTTNER, F.1 aWRIESSNIG, K.1 aRENNHOFER, H.1 aLICHTENEGGER, H.1 aNOVOTNY, E.
