Abstract
A study of olive stones pyrolysis over a wide range of temperatures, from ambient temperature up to 1123 K, has been carried out. Variations of chemical compositions and textural features taking place during olive stones pyrolysis have been determined. Porosity development with increasing pyrolysis temperature has been established from adsorption measurements employing nitrogen at 77 K and carbon dioxide at 298 K. Virgin olive stones and pyrolyzed samples structure modifications have been visualized by optical and scanning electron microscopy, respectively. Isothermal and non-isothermal thermogravimetric analysis has been carried out to examine pyrolysis kinetics. A recent model presented in the literature has been successfully applied to describe experimental data. Kinetic parameters have been estimated and compared with others reported for lignin. Both activation energy and preexponential factor have been found to increase with temperature.
