“…The second stage includes the decomposition of lignin and the combustion of the charcoal produced at the preceding stage (Fang et al, 2006). The same phenomena were observed and recorded by other authors as well (Branca and Di Blasi, 2004;Safi et al, 2004;Shen et al, 2009). 20 In order to compare biomass thermal behavior, DTG is frequently used to determine several temperature indexes: ignition temperature (Ti), final temperature of the first process (Tf1), final temperature of the second process (Tf2).…”

“…Due to a large number of complex reactions involved in the pyrolysis process, different model approaches have been proposed for the analysis of pyrolysis kinetics and mechanism such as the global kinetics model [7], the Brodi-Shafizadeh model [8], the two-parallel reactions model [9], and the three pseudocomponents model [10]. In this study, the two-parallel reactions model was adopted and used to describe the pyrolysis mechanism.…”

Pyrolysis of biomass including palm shell, palm kernel, and cassava pulp residue was studied in a laboratory free-fall reactor with three separated hot zones. The effects of pyrolysis temperature (250-1050 ∘ C) and particle size (0.18-1.55 mm) on the distribution and properties of pyrolysis products were investigated. A higher pyrolysis temperature and smaller particle size increased the gas yield but decreased the char yield. Cassava pulp residue gave more volatiles and less char than those of palm kernel and palm shell. The derived solid product (char) gave a high calorific value of 29.87 MJ/kg and a reasonably high BET surface area of 200 m 2 /g. The biooil from palm shell is less attractive to use as a direct fuel, due to its high water contents, low calorific value, and high acidity. On gas composition, carbon monoxide was the dominant component in the gas product. A pyrolysis model for biomass pyrolysis in the free-fall reactor was developed, based on solving the proposed two-parallel reactions kinetic model and equations of particle motion, which gave excellent prediction of char yields for all biomass precursors under all pyrolysis conditions studied.

“…There are only a few DSC studies in the literature concerning the thermal decomposition of lignocellulosic materials which is preferably studied by TGA (Bilbao et al, 1997;Branca & Di Blasi, 2003;Safi et al, 2004;Liodakis et al, 2005;Pappa et al, 2006;Liodakis & Kakardakis, 2008;Pappa et al 2004). We recorded the emitted heat flow vs. temperature with a power compensated DSC (Perkin Elmer®.…”
