Abstract

In this work a kinetic analysis was performed to investigate the energy potential of abundant agricultural residues: date residues olive stones and spent coffee grounds. The TGA experiments were carried out from room temperature to 700C under an inert atmosphere at different heating rates of 5 10 15and 20C.min-. Friedmans method seems to be the most appropriate because it contains no mathematical approximation that reduces the systematic error. The average activation energies obtained with the Friedman model are 159 168 201 and 170 kJ.mol- for date stems date seeds olive stone and spent coffee grounds respectively.
