The thermal decomposition behaviour of palm kernel shells of Ceroxylon quindiuense was studied using thermogravimetric analysis coupled to mass spectroscopy. Several temperature programs were used to study high and mild temperature thermal decomposition of this lignocellullosic material, including low and fast heating rates and step isothermal programs. Two significant events were observed by thermogravimetric analysis (figure 1), whereas several events were observed using mass spectroscopy. Some of the events found in the m/z intensity vs time curves occurs at the similar temperatures founds in the DTG curves but others only appear in the mass spectroscopy curves. The data were analyzed using distributed Energy Activation models and new data are reported for this material.
