Study of the Pyrolysis of Biofuels Pellets Blended from Sawdust and Oleic by-Products: A Kinetic Study

This work aims to study the slow pyrolysis of agro-pellets produced from olive mill solid waste blended with pine sawdust. Theunogravimetric analyses were conducted under inert atmosphere (N-2) at different heating rates (5 degrees C.min(-1), 10 degrees C.min(-1), 20 degrees C.min(-1) and 40 degrees C.min(-1)) in order to assess the thermal degradation behaviour of the produced agro-pellets. We observed that the different pellets thermal degradations follow the usual behaviour of lignocellulosic materials. Moreover, the kinetic parameters such as the activation energy (E-A) and the pre-exponential factor (A) values were evaluated based on two models. These kinetic parameters are close to those reported in the literature. Hence, the thermo-physical and chemical properties of the produced biofuels promote them as promising alternative fuels for producing energy in domestic or in industrial implementations of heat and or electricity.
