The increasing demand for renewable energies leads to a necessary diversification of combustibles among which are biomasses. The present study focuses on the kinetic analysis of grape marc as a new potential resource. The pyrolysis and the combustion of wine residues are first studied from an experimental point of view, through a thermogravimetry analysis. An extended IPR model based on a biomass lignocellulosic representation is then proposed which is proved to simulate with a great accordance the thermal decomposition of grape marc considering both devolatilization and char combustion. The resolution of the equations of this model and the determination of the optimal set of kinetic constants are performed using a numerical procedure based on Scilab routines. Different heating rates have been considered and their influence on the decomposition of the grape residues is examined. (C) 2014 Elsevier B.V. All rights reserved.
