Abstract
The pyrolysis and combustion of solid residues from olive oil processing were studied by dynamic TG–DTG at heating rates between 5 and 20 °C min −1 at atmospheric pressure. Two different atmospheres were used: on the one hand, an inert atmosphere (He) in order to study the pyrolysis of the material, and on the other hand an oxidative atmosphere (He:O 2 in different ratios) to study its combustion. Pyrolysis follows a two parallel and independent fractions model, with kinetic parameters typical of holocelulose (12%) and lignin (48%). Combustion adds a third reaction to the model, which is cocurrent, due to the combustion does not start until the main devolatilization is finished, attaining kinetic parameters and reaction orders typical of a gasification reaction.
