Ronda Department of Chemical Engineering, Avenida Fuentenueva s/n., University of Granada, 18071 Granada, Spain GR APHICAL A BSTRACT ARTICLE I NFO ABSTRACT Keywords: This paper presents a kinetic analysis of thermal decomposition of olive tree pruning from its basic compounds in Chemical Fractionation pyrolysis and combustion reactions. Experiments were performed by TGA under inert and oxidant conditions Combustion and results indicated that the decomposition of the olive tree pruning was related to the material composition. Olive tree pruning Pseudo-mechanistic models were proposed estimating the yield of pyrolysis on its basic compounds (hemi- Pyrolysis celluloses, cellulose and lignin). Validity and reliability of the proposed kinetic models were veriﬁed by the good Thermogravimetric analysis ﬁtting between the simulated and experimental curves (with values of R higher than 0.99 in most cases). Valorization Moreover, during the fractionation process, an acid fraction was obtained with great fuel properties, a high caloriﬁc value and a low residue after its combustion. 1.
